KABUL, Feb. 16 (Xinhua) -- At least four militants of terrorist groups were killed following airstrikes in two eastern Afghan provinces on Friday, said the command of special forces.

"Three members of al-Qaida network were killed as a result of an airstrike launched by Afghan Special Operations Forces in Chapa Dara District, Kunar province. One bunker of the terrorist network was also destroyed," Operational Coordination Group Afghanistan (MoD-OCGA) said in a statement.

In neighboring Nangarhar province, a militant of the Islamic State (IS) group was killed after an air raid in Achin district, according to the statement.

The sorties occurred at around midday and details on identities of the killed militants were not immediately available, but the statement noted that "more information will be shared with the media as appropriate."

The Afghan security forces, alongside U.S. and NATO-led coalition forces, have increased ground and air offensives against militants in the last few months as the militants keep attacking government interests across the country.
