JALALABAD, Afghanistan -- About 29 Islamic State (IS) militants were killed and a radio station belonging to the militant group was destroyed after US-led coalition forces carried out airstrikes in Afghanistan's eastern province of Nangarhar overnight, sources said on Tuesday.

"The foreign forces conducted four air raids against IS positions in Momand Dara locality of Achin district Monday night, killing 29 IS militants and destroying an IS radio station," the provincial government said in a statement.

Those killed included five workers of the banned group's radio station and five persons in charge of Internet service of the extremist group, the statement added.

Several high-ranking IS members were also killed by the airstrikes in the provincial capital city Jalalabad, 120 km east of Kabul.

The IS militants have been using the so-called Voice of Caliphate radio since late last year, for warning people not to support the government and recruitment of foot soldiers.

The US drones continued to hovering over Jalalabad and Achin district Tuesday morning, according to locals.

The district bordering Pakistan has been the scene of heavy clashes between IS militants and security forces backed by the pro-government local militiamen over the past couple of months.
