KABUL: Five rockets hit a major US air base in Afghanistan on Thursday (Apr 9) but there were no casualties, Afghanistan's NATO-led force said, in an attack claimed by the Islamic State militant group.
The attack comes weeks after Taliban militants and the United States reached a deal on the withdrawal of US-led international troops in exchange for Taliban security guarantees. Islamic State militants have not been included in the pact.
"Five rockets were fired at Bagram airfield early this morning," the NATO-led mission, Resolute Support, said on Twitter, referring to the main US air base in Afghanistan, north of Kabul.
"There were no casualties."
Islamic State said in a statement on social media that their fighters had targeted a helicopter landing pad at Bagram.
A Taliban spokesman said on Twitter that his group was not behind the attack.
The Afghan affiliate of Islamic State, known as Islamic State Khorasan (ISIS-K), after an old name for the region, first appeared in eastern Afghanistan in 2014, and has since made inroads into other areas, particularly the north.
The U.S. military estimates their strength at 2,000 fighters. Some Afghan officials estimated the number is higher.
IS militants, who battle foreign and Afghan government forces as well as the Taliban, have carried out some of the deadliest attacks in Afghanistan's urban centres in recent years.
The Taliban, as part of their agreement with the United States, have promised to open peace talks with the U.S.-backed Afghan government but little progress has been made.
The Afghan government has begun the release of Taliban prisoners from a jail near the Bagram base, as step to build confidence for the Taliban talks.
A hundred Taliban members are scheduled to be freed on Thursday from detention at a jail near the base, following the release on Wednesday of 100 Taliban members.
The prisoner exchange deal provides for the government to free 5,000 Taliban prisoners, with the Taliban releasing 1,000 members of the Afghan security forces in exchange.
