KANDAHAR, Afghanistan (AP) - At least three suicide bombers

attacked a police training center Monday in southern Afghanistan's

largest city, but the assailants were killed before they could

inflict any other casualties, officials said.

The midday attack started with a blast that could be heard

throughout much of Kandahar city.

One of the three attackers managed to blow through a defense

wall as he detonated his explosives, said Gen. Gul Nabi Ahmadzai,

head of police training programs for Afghanistan. The two remaining

bombers were shot dead when they engaged police in a gunbattle

while trying to enter the compound, he said.

There were no casualties among police trainers or officers

inside the compound, Ahmadzai said.

NATO and Afghan forces swarmed the training center, but it

appeared to be secure about an hour after the explosion. No more

gunshots could be heard.

A spokesman for the governor of Kandahar province gave a

slightly different account. Zulmai Ayubi said that the first blast

came from a car bomb driven into the wall by one of the assailants.

An officer reached inside the compound during the fighting said

there were four attackers, two of whom had managed to detonate

their explosives. He spoke anonymously because he was not an

authorized spokesman.

Taliban spokesman Qari Yousef Ahmadi claimed responsibility for

the attack, saying they sent four bombers. The Taliban have struck

the city recently with a slew of bombings and assassinations of

people seen as government allies - in a counteroffensive to a NATO

push into their southern strongholds.

NATO has pledged to make the coming offensive a combination of

military strikes and government-boosting programs it hopes will win

over the population.
