At least three people were killed and 79 injured in an attack in Kabul on Saturday, Afghanistan’s Ministry of Public Health said.
The injured have been taken to hospitals across the Afghan capital, said ministry spokesman Wahid Majroh.
Witnesses told CNN that the explosion came from a car bomb in front of the old Ministry of Interior building.
Taliban spokesman Zabiullah Mojahid claimed responsibility for the attack.
The blast comes a week after gunmen attacked the Intercontinental Hotel in Kabul, killing at least 22 people during a 12-hour standoff with security forces.
Of those killed, 14 were foreign nationals and eight were Afghans, according to the Ministry of Interior. Six gunmen were killed by Afghan security forces. The Taliban claimed responsibility for the assault.
On Wednesday, ISIS militants attacked the offices of British aid agency Save the Children in the eastern Afghan city of Jalalabad, killing at least four people and injuring dozens.
