Officials in Pakistan say three suspected U.S. drone strikes have killed at least 16 suspected militants in the North Waziristan tribal district on the Afghan border.
Intelligence officials told RFE/RL's Radio Mashaal that separate drone attacks were carried out in the Makai, Danda, and Deri Nashter areas of the Shawal mountains spanning the Afghan and Pakistani borderlands.
The strikes came a day after Pakistani officials summoned a U.S. diplomat to protest such attacks, which Pakistan views as "unlawful."
Attacks by unmanned U.S. aircraft are unpopular among Pakistan's anti-Western religious political parties.
American officials have said they believe the attacks are an important tool to counter anti-U.S. militants.
Many operatives of Al-Qaeda, Taliban, and other extremist Islamic groups have been killed in such strikes.
