Afghan border police say a suicide car bomber has attacked a police post in southeastern Afghanistan, near the Pakistani border.
There are conflicting reports about the casualties, but officials said the attack in Spin Boldak on Thursday wounded at least four police officers and one civilian. Two reports said one of the policemen later died.
Police officials said the driver blew up his vehicle as he approached a police position. Spin Boldak is one of the major border crossing points between Afghanistan and Pakistan.
A Taliban spokesman claimed responsibility for the attack.
Elsewhere in southern Afghanistan, NATO says a British pilot suffered minor injuries when his fighter jet crashed after takeoff in Kandahar province.
A NATO spokesman says the pilot ejected from the aircraft and was taken to a medical facility. He said the crash did not appear to be the result of hostile fire.
