Pakistani officials are rejecting claims that local villagers were killed in an overnight attack on a suspected pro-Taleban militant compound.
Pakistani military officials say soldiers backed by helicopter gunships killed about 30 militants at the compound in North Waziristan near the Afghan border.
A Pakistani general ,Shaukat Sultan said the troops also destroyed a huge cache of weapons and explosives.
The operation happened in an area where a curfew was lifted only hours earlier following six days of clashes that left more than 100 militants dead.
Local residents said the compound near Miran Shah was owned by a cleric who is considered to be pro-Taleban, Maulvi Sadiq Noor. Some residents said local villagers were killed in the attack, and not militants.
Security forces have been searching for Noor for several days following a military attack on an al-Qaida hideout in the area that led to the clashes.
