Kabul: Roadside bombs killed four Afghan police officers on Saturday in suspected Taliban militant attacks, officials and a witness said.

A remote-controlled bomb destroyed a police vehicle in the Waghaz district of central Ghazni province, said deputy provincial police chief Mohammed Zaman.

An Associated Press Television News cameraman at the scene saw three burned, mutilated corpses. Four other police were wounded and taken to hospital.

In western Farah province, a bomb blast hit a police vehicle in Bala Buluk district, killing one officer and wounding another, provincial police chief Khalil Rahmani said.

There was no immediate claim of responsibility for the attacks, but Taliban militants often target Afghan police, who are less trained and worse equipped than the national army.
