Pakistani intelligence officials say three U.S. missile strikes have killed at least 11 suspected militants in the country's North Wazirstan tribal region.
The first drone strike Wednesday struck a vehicle near the town of Miran Shah, killing at least four militants. Hours later, officials said, a second attack killed three militants in the same region. And a third missile strike hit a vehicle in the Pai Khel area of North Waziristan, killing at least four suspected militants.
The United States has increased its use of missiles launched from unmanned aircraft against Taliban and al-Qaida-linked militants. There have been at least 40 such strikes since September in northwestern Pakistan near the Afghan border.
The U.S. does not publicly acknowledge the attacks, which often are criticized by Pakistani officials as a violation of their country's sovereignty.
