Afghan officials say suspected Taliban militants have killed seven police officers at a security checkpoint in the southern province of Kandahar.
A spokesman for the Kandahar governor says two men invited by police to eat at the checkpoint picked up weapons after dinner and opened fire.
The two attackers escaped the scene. Police say they were police officers.
The Taliban claimed responsibility for the overnight attack.
At least 14 Afghan soldiers and police have been killed this week in militant attacks targeting government security forces.
