A US double drone strike has killed 12 suspected militants in South Waziristan on the Afghan-Pakistan border.
The attacks targeted a compound and a seminary near Wana, the main town in the tribal district, officials said.
It came days after al-Qaeda operative Ilyas Kashmiri was reported to have been killed in a US strike in the area.
Militants in Pakistan have vowed to avenge his reported killing, as well as the death of al-Qaeda leader Osama Bin Laden last month.
On Sunday, at least 18 people died in a bomb blast at a bakery in the garrison town of Nowshera in northwest Pakistan.
Earlier, another bomb explosion at a bus stop on the outskirts of Peshawar killed six people. Both attacks are being blamed on the Pakistani Taliban.
Monday’s drone attacks targeted a compound and a religious seminary in the mountains near Wana, according to reports.
There were “foreigners” among those killed, say reports, though their identities were not immediately known.
United States officials do not routinely confirm that they have carried out drone attacks, but analysts say that only US forces have the capacity to carry out such strikes in the region.
More than 100 raids were reported last year in the troubled tribal areas along the Afghan border.
Many militants, some of them senior, have been killed in the drone strikes, but hundreds of civilians have also died.
Correspondents say that in the past the drone strikes have had the tacit approval of the Pakistani authorities, although Pakistani leaders always denied secretly supporting them.
In recent months, senior Pakistani security officials have reportedly been pressing for a limit to such operations.
