At least four people have been killed in a suicide attack on a military convoy in Pakistan's troubled North West Frontier Province.
The attacker rammed his vehicle into the convoy near a paramilitary camp in Charsadda district.
Three soldiers and a civilian were confirmed dead in the attack.
Pakistan's military has been conducting operations against Taleban militants and al-Qaeda fighters in several districts of the province.
The attack took place near the village of Subhankuh, close to the Shabqadar paramilitary camp about 30km (18 miles) north-west of the city of Peshawar.
Eyewitnesses told reporters that the attacker was riding on a motor-cycle.
The convoy was carrying reinforcements to the Mohman tribal region near the Afghan border.
North-western Pakistan has seen a wave of violence against security forces.
On Monday at least nine people were killed in a suicide car bomb attack on a security checkpoint in the town of Mingora in the Swat valley. At least 40 people were injured.
