The Pakistani military says its latest airstrikes in a troubled tribal region near Afghanistan have killed 14 suspected militants.

The military says in a statement that 14 "terrorists" were killed in Saturday's airstrike in Shawal, a town in North Waziristan where the army launched a ground operation this month to eliminate local and foreign insurgents.

The military gave no details and did not elaborate on the nationalities or identities of the slain men.

The Pakistani army has been carrying out a major military operation in North Waziristan since June 2014 and it says security forces have cleared more than 90 percent of the region and killed more than 3,000 militants. The army has lost nearly 300 soldiers in the region in the past year.
