Pakistani security forces have attacked a militant hideout near the Afghan border, killing at least 15 guerrillas, the military says.
Helicopters and ground troops assisted in the operation
It says rockets and helicopters were used in Saturday's pre-dawn attack in the tribal region of North Waziristan.
Pakistani security forces have been battling Taleban and al-Qaeda supporters in the area.
An army statement said the targeted guerrillas had carried out recent attacks on security forces.
The attack on a suspected training camp was carried out in a highly co-ordinated operation, the military says.
According to a spokesman, 15 to 20 local and foreign militants died.
He said the attack followed intelligence that pro-Taleban militants were using the compound as a base for attacking military convoys.
Attacks on military
In recent weeks a series of grenade and rocket attacks on military convoys in North Waziristan has killed or wounded a large number of troops.
Many Pakistani soldiers have been killed by militants in recent weeks
In one such attack last week two suspected suicide bombers rammed their vehicle into a military truck, killing three soldiers.
The BBC's Zaffar Abbas in Islamabad says Pakistan's semi-autonomous tribal regions of North and South Waziristan have remained the biggest support base for Afghan insurgents.
Since the start of the military operation three years ago the Pakistani security forces have managed to kill or drive out most of the Arab and other foreign militants from the area.
But in recent months most of the local tribesmen have turned against the authorities and many of them are now fighting along the side of the Afghan Taleban, our correspondent adds.
Over the last three years, over 2,000 people have been killed in the region, including more than 300 troops.
