Pakistani police say a suicide bomber has killed eight paramilitary police in an attack on a security post in the capital, Islamabad.
Several other people were injured and emergency services are at the scene.
The attacker slipped into the base under cover of darkness while the police were dining and attacked a mess tent, also injuring a number of police.
This was the second attack on the security forces in Islamabad in two weeks.
A suicide bomb attack on a police station on March 23 left one policeman dead and another injured.
Violence in Pakistan has surged in recent months amid a wave of attacks blamed on Islamist militants.
