A suicide attacker detonated explosives Monday near major political offices in the Afghan capital of Kabul, killing at least six people, officials told CNN.
The attack took place near an office of the National Directorate of Security (NDS) close to Abdulhaq Square in Kabul police district nine, Nasrat Rahimi, deputy spokesman for the Interior Ministry, said. He said the attacker was targeting the NDS office.
The NDS office is close to the US Embassy, along with several other diplomatic missions.
Six civilians were killed in the blast, and one other person was injured in the attack, according to Ismail Kawosi, a spokesman for the ministry of public health.
No group has yet claimed responsibility.
Attacks on both official and unofficial targets are commonplace in Kabul and throughout Afghanistan. Last month, gunmen stormed a television station in the capital, killing a security guard and injuring five others, including four firefighters.
The siege ended after a three-hour standoff with police which left all the attackers dead, Kabul police said.
In October, dozens of Afghans were killed in two mosque attacks, claimed by ISIS, only to be followed the next day by a suicide bombing near a military academy which took another 15 lives.
Also in October, at least 41 soldiers were killed in an attack on their base in eastern Afghanistan.
In September a suicide bomber killed three people in a blast outside a cricket stadium in Kabul, and the month before ISIS claimed responsibility for an attack on a Shiite mosque in the Afghan capital, which left 20 people dead.
