KABUL, Afghanistan -- A suicide bomber killed three Afghans on Wednesday in an unsuccessful attempt to enter an American military base in eastern Afghanistan, American and Afghan officials said.
The attack on Forward Operating Base Chapman, located at an old military airfield just outside Khost, came almost exactly three years after another suicide attacker succeeded in entering the base and killed eight people, most of them C.I.A. employees, in the deadliest episode for the agency during the Afghan war.
Gen. Abdul Qayum Baqizoi, the police chief in Khost Province, said the attacker drove a minivan packed with explosives toward the front gate as civilian workers gathered to enter at the start of the day, but was stopped by an Afghan guard. The attacker detonated his explosives and killed the guard, as well as two civilians, General Baqizoi said.
A spokesman for the NATO-led International Security Assistance Force confirmed the episode but said the three victims were all Afghan guards. He stressed that the security perimeter of the base had not been breached.
Seven civilians were wounded in the attack as well, General Baqizoi said.
A statement e-mailed to journalists by a Taliban spokesman, Zabiullah Mujahid, claimed responsibility for the attack. "According to credible information there were up to 250 national enemies queuing in front of the gate to get inside and serve the Americans in return for dollar salaries, and by doing so they were playing with their country, religion and dignity," Mr. Mujahid said.
