Four Afghan police officers were killed and five wounded when their car was hit by a blast in the central province of Uruzgan on Tuesday, officials said, in an attack for which Taliban guerrillas claimed responsibility. Provincial governor Jan Mohammad Khan said that Mohammad Ibrahim Akhunzada, the security chief of the province's Chorah district, was among the wounded. He said the blast was caused by a roadside bomb, but provincial police chief Rozi Khan blamed a landmine. Rozi Khan said the blast happened about 2 km (1 mile) from the town of Deh Rawud.
