Afghan police defectors return to fold, kill seven colleagues

KANDAHAR, Afghanistan (Reuters) - Two Afghan police officers who had recently rejoined the force after defecting to the Taliban, shot dead seven of their sleeping colleagues on Tuesday, a police chief said.

The killings came during a particularly bloody 24 hours for Afghan forces, with another 16 soldiers, police and bodyguards killed in different attacks, underscoring concern about government forces as foreign troops prepare to leave.
