American officials face barrage of criticism from Human Rights Council over Guantanamo and torture allegations.
Intelligence officials in northwestern Pakistan say US drone attacks have killed 14 fighters in the region.
Two missile attacks against the suspected al-Qaeda and Taliban targets took place an hour apart in North Waziristan on Sunday, they said.
The first missile struck a house and the second one hit a vehicle in the town of Ghulam Khan, just north of Miranshah, the intelligence officials told the AFP news agency on the condition of anonymity. Nine suspected fighters were killed in the attacks, they said.
Another pair of missiles hit a vehicle in the nearby town of Datta Khel, killing another five people.
A covert US campaign of drone attacks in Pakistan has intensified in the region in the wake of intelligence claims last month of a plot to launch attacks on European cities.
More than 200 people have been killed in at least 40 raids in Pakistan’s northwest since September 3.
Sunday’s attacks came as Barack Obama, the US president, was visiting neighbouring India. He is not scheduled to travel to Pakistan during his Asia tour.
