A bomb blast killed at least two workers and wounded 37 today after six Taliban militants wearing suicide vests attacked the gate of the Afghan intelligence headquarters in Kabul.
A Taliban spokesman claimed responsibility for the attack in which all six assailants died.
Kabul police said the first attacker detonated his bomb at the front gate of the NDS compound and the other five, all wearing bombs strapped to their chests, piled out of a van and tried to storm the gate.
All were killed, a police statement said, adding that the van was also loaded with explosives, which did not detonate and were later defused by police.
The explosion occurred at about noon local time and was followed by volleys of gunfire for the next 30 minutes.
It was the second attack aimed at the intelligence agency in two months.
