Pakistani officials say at least 25 militants have been killed in air strikes in the troubled North Waziristan tribal district.
Unidentified security officials said the strikes were carried out on January 8, destroying several militant hideouts and vehicles.
Five of those killed were members of the extremist Haqqani network, 10 were Uzbek and Chechen militants, and 10 were from the Tehrik-e Taliban, one official was quoted as saying.
Pakistan has been carrying out a major offensive against extremist groups in North Waziristan neighboring Afghanistan since 2014.
The military says more than 3,600 militants and 350 soldiers were killed in the operation.
The area is off-limits to journalists, making it difficult to independently verify the number and identity of those killed.
