United States president Joe Biden has threatened more action on ISIS-K over the Kabul attack that killed over 60 Afghans and 13 U.S. troops saying “we’re not done with you yet.”

His remarks come after ISIS-K has claimed responsibility for suicide bombings at Kabul airport last Thursday. Watch a Sky News video for more details.

The U.S. military has already conducted a drone strike against an Islamic State member in Afghanistan’s Nangahar Province, which borders Pakistan in retaliation to the Kabul bombing.

Captain Bill Urban, the spokesman for U.S. Central Command, said the U.S. airstrike killed an Islamic State “planner.”

It is not clear whether the planner killed by the US had been involved in Thursday’s attack near the city’s airport, where thousands of people had been trying to reach evacuation flights to escape the incoming Taliban regime.

The Kabul bombing came as the U.S. was in the final days of evacuating its personnel from Afghanistan following a two-decade-long war with the Taliban.
