A suicide car bomber attacked a police station near Afghanistan''s border with Pakistan on Thursday, wounding four officers, an official said.

The blast in Kandahar province''s Spinboldak district killed the car bomber but there were no other deaths, said Police Commander Gen. Abdul Raziq.

Taliban spokesman Qari Yousuf Ahmadi claimed responsibility for the attack in a phone call to The Associated Press.

Spinboldak sits in the southeast corner of Afghanistan, an area where the Taliban often wield more control than the government. Many of the 21,000 additional U.S. troops deploying to Afghanistan this summer will spread out across the south as the U.S. tries to regain control of a war that it once thought it had won.

This week, President Barack Obama put his stamp on the bloody eight-year conflict by replacing the general in charge of the effort and installing a new ambassador. The Obama administration hopes the leadership shake-up will help reverse the militants'' momentum.
