Washington: US military took a drone strike on Friday against Islamic State-Khorasan, the group which claimed credit for the deadly suicide bombing at Kabul airport. Central Command Captain Bill Urban said the unmanned airstrike occurred in the Nangarhar Province of Afghanistan.

He said initial indications are that we killed the target. In a statement he said that we know of no civilian casualties, the first reported US strike since the attack. The strike, launched from outside of Afghanistan, came as the airlift of evacuees from Kabul airport continued under much heightened security after Thursday’s attack.

Pentagon spokesman John Kirby said on Friday that they believe the group planned to strike the airlift again. We still believe there are credible threats, specific, credible threats, he said.
