Pakistani security officials say U.S. drone strikes in northwestern Pakistan have killed at least 15 people, most of them militants.
There were three drone attacks reported Saturday in the North Waziristan tribal region, a suspected hideout for al-Qaida and Taliban fighters.
Authorities say the first attack killed at least seven people. It was followed by a drone strike that left at least four people dead. The third strike killed four militants when it struck their vehicle near Miranshah, the main town in North Waziristan.
The strikes come a day after a missile attack in the same area killed at least five people.
North Waziristan, located near the Afghan border, is a frequent target of U.S. missile strikes because al-Qaida and Taliban leaders are believed based there.
