Pakistani intelligence officials say two missiles fired from a U.S. drone hit a compound in a troubled Pakistani tribal region near the Afghan border, killing three militants.

The two officials, who spoke on condition of anonymity because they were not authorized to brief reporters, said Tuesday that the latest strike happened Monday night the Shawal village of North Waziristan tribal region.

North Waziristan has been the scene of a massive military operation against local and foreign militants since June and the military says it has eliminated militants in most of the areas of North Waziristan since launching the operation. The military says it has killed more than 1,200 militants in the operation.

U.S. drone strikes have killed several top Pakistani Taliban and al-Qaida militants in the region over the years.
