The bomber evaded several rings of Afghan police and detonated his explosives on the doorstep of the international military headquarters, an assault possibly aimed at sending the message that the Taliban can attack anywhere as Afghans gear up for their second-ever direct presidential election. Militants have warned Afghans not to vote and have threatened to attack voting sites.
The NATO headquarters - where top commander U.S. Gen. Stanley McChrystal is based
- sits beside the U.S. Embassy and shares the same street as the presidential palace. The explosion was the first major attack in Kabul since February, when eight Taliban militants struck three government buildings simultaneously in the heart of the city, an assault that killed 20 people and the eight assailants.
Afghanistan has braced for attacks ahead of the election. International workers in the country were planning on working from home over the next week or had been encouraged to leave the country. U.S., NATO and Afghan troops were working to protect voting sites, particularly in regions where militants hold sway.
President Hamid Karzai condemned the attack and said Afghans knew the importance of Thursday's election.
"The enemies of Afghanistan, by conducting such attacks, are trying to create fear among the people as we get close to the election," Karzai said in a statement. He said Afghans "are not afraid of any threats, and they will go to cast their votes."
Bloodied and dazed Afghans wandered the street after Saturday's blast, which rattled the capital and sent a black plume of smoke skyward. Children
- many of whom congregate outside the NATO gate to sell gum to Westerners - were among the wounded. Windows of nearby antique shops were shattered and blood smeared the ground.
The Taliban claimed responsibility and said the target was the NATO headquarters and the U.S. Embassy some 150 yards (meters) down the street. A top Kabul police official blamed al-Qaida.
Brig. Gen. E. Tremblay, the spokesman for the NATO-led force, said some soldiers in the International Security Assistance Force were wounded in the 8:35 a.m. blast. He did not say how many. The explosion occurred 30 yards (meters) from NATO's front gate, he said. Pointing to the civilian casualties, Tremblay said the Taliban were "indiscriminately killing civilians."
Afghan security forces stopped the vehicle in front of NATO headquarters, and then the bomber detonated the explosives, Tremblay said.
"The security measures in place have stopped cold the bombers as planned," he said, calling the latest attack an example of the "residual risk" that remained despite the safety measures taken. "It's very difficult to stop a suicide bomber."
The blast killed seven Afghans and wounded 91, Gen. Mohammad Zahir Azimi, the spokesman for the Afghan Ministry of Defense, said.
Four Afghan soldiers and Awa Alam Nuristani, a member of parliament and President Hamid Karzai's campaign manager for women, were among the wounded, the ministry said.
"I was drinking tea in our office when a big explosion happened," said Abdul Fahim, an Afghan in his mid-20s who sustained leg injuries. "I lay on the ground and then I saw wounded victims everywhere, including police and civilians."
