At least 22 people have been killed and 70 wounded in twin bombings near the Afghan parliament in Kabul, officials say.
Minutes after the blasts, a Taliban spokesperson said the group carried out the attack, targeting members of the Afghan intelligence agency.
Most of the victims are said to be civilians, including parliament staff.
Reports speak of a suicide bomber on foot followed by a car bomb.
Afghan sources said a district head of the National Directorate of Security – Afghanistan’s main intelligence agency – was among the dead.
Waheed Majroh, an Afghan health ministry official, told the BBC that the wounded were taken to Istiqlal and Emergency hospitals.
Initial reports suggest the attack is the bloodiest to strike Kabul for several months.
An injured parliament security guard named as Zabi told AFP: “The first explosion happened outside the parliament… a number of innocent workers were killed and wounded. It was caused by a suicide bomber on foot.”
He said the car containing a bomb “was parked on the other side of the road and flung me back when it detonated.”
Ahmad Wali, police chief of Kabul’s district 7, told the BBC the second bomb went off when police went to help the victims of the first.
He said the explosions were close to the gates of the city’s American University.
