Three policemen have been shot dead near the Pakistani capital Islamabad.
A police spokesman said the bodies of the dead men were discovered early Sunday.
He said the men were apparently shot in their sleep, each by a single bullet to the head.
The men were guarding a railway bridge in Hasan Abdal, a town 40 kilometers west of Islamabad.
The police spokesman refused to comment on whether the slayings were a criminal act or an attack linked to the Taliban, who frequently target police and security forces.
Some information for this report was provided by AFP and AP.
