Latest information released by Afghanistan Interior Ministry on the suicide attack that shocked the country's capital Kabul Tuesday morning showed two people, including the bomber, were killed and seven others wounded.
"In the attack carried out by the enemies of peace, one civilian was martyred and seven others including five employees of an office of Afghan Defense Ministry were injured," an official at the press department of Afghan Interior Ministry told Xinhua.
The official, who refused to be named, said press release would soon be issued to the media.
In the powerful blast which occurred at 7:40 a.m. (0310 GMT) close to the office of the international relation department of the Afghan Defense Ministry, three Land Cruisers of the U.S. military were also damaged.
However, the official did not comment on if there were any casualties on American servicemen.
The incident took place in the central Kabul's Wazir Akbar Khanarea where several embassies and the branches of international agencies are located.
Both Taliban outfit and Hekmatyar-led outlawed Islamic party the Hizb-e-Islami have claimed responsibility for the attack.
Taliban purported spokesman Zabihullah Mujahid told media from an unknown location that a loyalist to Taliban from Kabul province carried out the attack while Hekmatyar-led group said that Qari Mansoor committed the bombing to punish foreigners.
It was the fifth suicide bombing and explosions in and outside Kabul since early weekend that left over a dozen persons including one NATO soldier dead while majority of the victims were civilians.
More than 5,800 people have been killed in conflicts and militancy-related violence over the past 11 months in war-torn Afghanistan.
