Afghan police kill six colleagues in checkpoint shooting
Six police officers have been shot and killed by colleagues who turned their guns on them at a checkpoint in Afghanistan, police said.
Mohammad Hasham, head of police in the Charchino district, said the shooting happened in the early hours of Saturday in the volatile southern Uruzgan province.
Three officers involved in the shooting managed to escaped, taking weapons and vehicles with them, he said.
The incident follows another in the capital Kabul on Friday, when an Afghan security guard at a UN compound shot two Nepalese guards, killing one and wounding the other.
In southern Zabul province on Thursday, eight policemen were shot dead by a colleague.
The Taliban, who have been fighting the Kabul government for 15 years, are often behind such attacks.
