Twelve suspected militants died in a missile strike on a home in northwestern Pakistan on Tuesday, officials said.

The attack occurred after midnight in Khushali Torikhel, a village in North Waziristan, a tribal region bordering Afghanistan, an intelligence and a government official in the region said.

There was no immediate official confirmation of the attack. The two officials who spoke did so on condition of anonymity because they were not authorized to make media comments.

Pakistan has been trying to tamp down on militancy in its border regions, where elements of Al Qaeda and the Taliban are believed to operate.
