KABUL, Afghanistan - The death toll from a suicide bombing at an Afghan police headquarters rose by one to 13 on Sunday after men disguised as officers made it through three security gates before detonating their explosives.

Afghan officials launched an investigation into the attack on Saturday in eastern Afghanistan. All those killed were policemen.
