When a married couple killed 14 people in San Bernardino, California, they committed the deadliest terrorist attack on U.S. soil since September 11, 2001.
The assault also underscored an unsettling reality: ISIS has morphed from a scourge affecting Iraq and Syria to a threat to people around the world.
Since declaring its caliphate in June 2014, the self-proclaimed Islamic State has conducted or inspired nearly 60 terrorist attacks in 19 countries that have killed at least 1,150 people and injured more than 1,700 others.
One San Bernardino killer pledged allegiance to the ISIS leader, investigators say. And ISIS hailed the attackers as “martyrs” and “supporters.”
Did ISIS actually order the attack? Did its ideology inspire the killers?
It can be difficult at times to divine the precise role that international terrorists play in this or that attack. The person who killed four U.S. Marines and a sailor in Chattanooga, Tennessee, in July 2015, for example, was “motivated by foreign terrorist organization propaganda,” FBI Director James Comey says, though he added that it’s hard to say which terrorist group motivated the killer.
Yet one thing is clear: The deadly tentacles of ISIS have spread quickly, from the terrorist group’s epicenter in parts of Iraq and Syria to points around the globe.
Here’s a look at terrorist attacks outside Iraq and Syria believed to have been inspired or conducted by ISIS or its regional affiliates, along with context about the known connections to ISIS:
NORTH AMERICA
October 20, 2014 – Martin Rouleau-Couture runs over two soldiers, killing one, outside a government office in Saint-Jean-sur-Richilieu, Quebec. Rouleau-Couture had converted to Islam and expressed support for ISIS online. He may have been responding to ISIS spokesman Abu Muhammad al-Adnani’s call to arms, according to the Institute for the Study of War. ISIS mentioned Rouleau-Couture in its English-language magazine Dabiq, claiming the attack resulted from Adnani’s call. It also included a picture of Rouleau-Couture in the magazine. The attack is believed to have been inspired by ISIS.
October 22, 2014 – Gunman Michael Zehaf-Bibeau opens fire at Canada’s National War Memorial and Parliament Hill in Ottawa, killing army reservist Cpl. Nathan Cirillo. Zehaf-Bibeau is killed by House of Commons Sergeant-at-Arms Kevin Vickers. Two others, including a security guard, are injured. ISIS mentioned Zehaf-Bibeau in Dabiq, claiming that the attack was the “direct result of (Adnani’s) call to action,” the Institute for the Study of War reported. The attack is believed to have been inspired by ISIS.
October 23, 2014 – A man with a hatchet attacks four police officers in New York. Police said the attacker, a U.S. citizen named Zale Thompson, was self-radicalized. Thompson had searched online for information on beheadings, al Qaeda, ISIS and al Shabaab, according to police. ISIS mentioned Thompson in Dabiq, according to the Institute for the Study of War. The attack is believed to have been inspired by ISIS.
May 3, 2015 – Two men open fire outside a Prophet Mohammed cartoon contest in a Dallas suburb. The gunmen, Elton Simpson and Nadir Soofi, wound a security guard before police shoot and kill them. Simpson linked himself to ISIS in a tweet posted before the attack, according to a federal law enforcement source.
The keynote speaker at the event was right-wing Dutch politician Geert Wilders, who was on an al Qaeda hit list. At least one of the gunmen appeared to have been in contact with an ISIS operative in Syria via social media. ISIS claimed responsibility, describing the attackers as “soldiers of the caliphate,” according to the Institute for the Study of War. The institute described the attack as “ISIS-inspired,” and U.S. officials said the group probably was being “opportunistic” in claiming responsibility. The attack is believed to have been inspired by ISIS.
December 2, 2015 – Tashfeen Malik and her husband, Syed Rizwan Farook, shoot 14 people to death and injure 21 others at a gathering of local government health workers in San Bernardino, California. Malik and Farook are gunned down in a shootout with law enforcement.
Malik pledged allegiance to ISIS leader Abu Bakr al-Baghdadi on Facebook, three U.S. officials familiar with the investigation told CNN.
The husband-and-wife team had developed extremist views as early as 2013, a time that predates the rise of ISIS, FBI Director Comey has said. And Farook tried to contact other terrorist groups, a senior law enforcement official said.
“Individuals inspired by the Islamic State of Iraq and al Sham (ISIS) and with links to al Qaeda conducted the terrorist attack,” according to the Institute for the Study of War. “This attack was the first al Qaeda- or ISIS-related in the U.S. by a skilled shooter team using both guns and explosives.” The attack is believed to have been inspired by ISIS.
January 8, 2016 – A man identified as Edward Archer is arrested after a Philadelphia police officer is shot and wounded. Officer Jesse Hartnett was hit three times and suffered “some very serious injuries that will require multiple surgeries,” Philadelphia Police Commissioner Richard Ross said. Despite being seriously injured, Hartnett got out of his patrol car and shot the assailant, who later was apprehended by other officers, Ross said.
Archer claims to have committed the attack on ISIS’ behalf, telling police: “I pledge my allegiance to the Islamic State, and that’s why I did what a did.” Archer has a criminal history and impending court appearances. He had traveled to Saudi Arabia and Egypt.
EUROPE
May 24, 2014 –Three people are killed and another seriously injured in a shooting at the Jewish Museum in Brussels, Belgium. The suspect was identified as Mehdi Nemmouche, a 29-year-old Frenchman from Roubaix in the Pas-de-Calais region of northern France. Nemmouche, who had spent a year in Syria, is a radicalized Islamist, according to the chief prosecutor of Paris.
Nemmouche was arrested with a Kalashnikov, a handgun, an audio recording claiming responsibility and a white sheet emblazoned with the name of the Islamic State of Iraq and the Levant, according to the Institute for the Study of War. The attack is believed to have been inspired by ISIS.
December 20, 2014 – A man stabs three police officers in the French city of Tours. The attacker was a 20-year-old French citizen who was born in Burundi. He was shot dead by police. CNN terrorism analyst Paul Cruickshank reported that the attacker had posted the ISIS flag on his Facebook page. The attack is believed to have been inspired by ISIS.
January 9, 2015 – Amedy Coulibaly is killed during a police rescue operation to end his siege at a kosher grocery store in Paris. Authorities say he killed four hostages. He allegedly shot a Paris policewoman the previous day. Coulibaly had pledged his allegiance to ISIS in a video made before the attack. He was a friend of Said and Cherif Kouachi, who killed 12 people two days earlier in an attack on the offices of Charlie Hebdo magazine in Paris. Al Qaeda in the Arabian Peninsula claimed responsibility for the attack at Charlie Hebdo.
Pro-ISIS sources circulated a video in which Coulibaly pledged allegiance to ISIS leader Baghdadi in front of an ISIS flag, according to the Institute for the Study of War. Investigators found ISIS flags, automatic weapons, detonators and cash in an apartment rented by Coulibaly outside Paris. The attack is believed to have been inspired by ISIS.
February 14, 2015 – A gunman attacks a free speech forum featuring a controversial cartoonist and then fires shots near a synagogue in Copenhagen, Denmark, killing two people and wounding five police officers.

The attack is believed to have been inspired by ISIS.
June 26, 2015 — A man on France’s terror watch list shoots selfies with the decapitated body of his boss before launching an attempted suicide attack at a U.S.-owned chemical factory near Lyon in southeastern France. Photos made with suspect Yassin Salhi’s phone may have been intended to become part of a social media propaganda campaign for ISIS, said Paris prosecutor Francois Molins.
The head was tied to the factory’s fence, along with two flags bearing “the Islamist profession of faith,” authorities said.
“We can note that this perfectly matches ISIS’ watchword, which regularly calls for committing terrorist attacks on the French territory, and to precisely slit the throats of the nonbelievers,” Molins said. “The beheading also precisely recalls this terrorist organization’s modus operandi.” The attack is believed to have been inspired by ISIS.
September 2, 2015 – ISIS announces that its affiliate in the Caucasus had launched an attack on a Russian military facility in southern Dagestan, a troubled Russian republic, claiming a number of Russian soldiers were killed or injured. There is no independent confirmation of the attack.

The attackers, armed with assault rifles and explosives, target six locations across the city — including a soccer match as France plays world champion Germany and the Bataclan concert hall, where most of the fatalities occur. In an online statement distributed by supporters, ISIS said eight militants wearing explosive belts and armed with machine guns attacked precisely selected areas in the French capital. The Institute for the Study of War described the attacks as the terror group’s “most sophisticated assault in the West to date.” It was the worst violence in France since World War II. The attack is believed to have been conducted by ISIS or one of its affiliates.
December 5, 2015 – A 29-year-old man attacks another man in the Leytonstone Underground station in London, England. He cut the man’s throat in a “sawing motion,” prosecutors said. The attacker was heard to shout, “This is for Syria, my Muslim brothers.” Britain’s Press Association said his cell phone contained images and flags associated with ISIS. Police said they were investigating the incident as a terrorist offense. The attack is believed to have been inspired by ISIS.
December 30, 2015 – An ISIS affiliate in the Caucasus says it carried out a gun attack in the city of Derbent in Dagestan, claiming to have killed a “Russian intelligence officer.” Reports from the region say a shooting at the ancient citadel in Derbent targeted a group of tourists and killed a security guard, injuring several others. The Islamic Emirate of the Caucasus pledged allegiance to ISIS in June 2015.
January 7, 2016 – A man is shot dead by police in Paris as he wields a large knife outside a metro station. A Paris prosecutor later says the man — thought to be Tunisian — had a sketch of an ISIS flag and had pledged allegiance to ISIS leader Baghdadi. “We might be confronted to highly organized networks like the one in November or we could also run into an isolated attack by a person with psychological problems,” says the prosecutor, Francois Molins.
THE MIDDLE EAST AND NORTH AFRICA
September 20 or 21, 2014 – French citizen Herve Gourdel is abducted in the Tizi Ouzou region of Algeria, east of Algiers. An online video days later shows militants beheading him and pledging loyalty to ISIS. In the video, armed men claim to belong to Islamist militant group Jund al-Khilafah — or Soldiers of the Caliphate — in Algeria. They pledge allegiance to Baghdadi. Jund al-Khilafah “stated in a video released on September 22 that the kidnapping was their fulfilling the order of IS spokesman Abu Muhammad al-‘Adnani to attack citizens of countries participating in the U.S.-led coalition against the IS,” according to INSITE on Terrorism, a blog of the SITE Intelligence Group.

Tunisian President Beji Caid Essebsi later confirmed that a third person took part in the museum attack and got away.
ISIS claimed responsibility. “The suicide gunmen attack on the Bardo Museum in Tunis … demonstrates how the confluence of ISIS and al-Qaeda elements in North Africa may lead to emergent threats in the region,” the Institute for the Study of War says.
“While both groups recruit heavily from Tunisia, the al-Qaeda affiliated Uqba Ibn Nafaa Brigade is the country’s strongest operational extremist group. However, the Bardo attack diverged from Uqba’s usual pattern of attacking security forces near its mountainous stronghold in western Tunisia, indicating that ISIS-linked elements likely played some role in the operation.” The attack is believed to have been conducted by ISIS or one of its affiliates.
