The strikes occurred just before midnight Tuesday in Bobar village in the South Waziristan tribal area, a stronghold of the Pakistani Taleban, said the officials, speaking on condition of anonymity because they were not authorized to talk to the media.
The two compounds were hit about 20 minutes apart, said the officials. It is unclear how many suspected militants were killed in each compound.
The Pakistani military conducted a large ground offensive against the Pakistani Taleban in South Waziristan in 2009, but militants remain in the area and periodic attacks still occur.
Earlier on Tuesday night, militants attacked an army checkpoint in the Ladha area of South Waziristan with rockets, killing one soldier and wounding another, intelligence officials said.
The area where the drone strikes occurred is very remote and has not yet been cleared by the military, said the intelligence officials. There has been at least one strike in this area before.
The US does not acknowledge the CIA-run drone program in Pakistan publicly, but officials have said privately that the strikes have killed many senior Al-Qaeda and Taleban commanders.
The Obama administration has ramped up the number of drone strikes in Pakistan’s rugged tribal region in the past few years. Most of the strikes have targeted Al-Qaeda militants or Afghan Taleban insurgents battling US forces in Afghanistan.
But the attacks have also killed Pakistani Taleban fighters, who are allied with Afghan militants but have focused their attacks inside Pakistan. A US drone strike killed Pakistani Taleban leader Baitullah Mehsud in 2009.
Pakistani officials have criticized the strikes as violations of the country’s sovereignty, but the government is widely believed to have supported the strikes in the past and even let the drones take off from bases inside Pakistan.
Pakistani criticism has been more muted when the attacks target members of the Pakistani Taleban or Al-Qaeda, rather than Afghan militants with whom the government has historical ties. Many analysts believe Pakistan sees the Afghan Taleban and their allies as potential partners in Afghanistan after foreign forces withdraw.
Also Wednesday, militants attacked a military checkpoint in the Murghan area of the Kurram tribal region, killing one officer and wounding a soldier, said Wajid Khan, a local government official. The military killed 15 militants in a retaliatory offensive, he said.
