Biden: US drone strike was 'not the last'

US President Joe Biden has pledged to take a tough stand against an Islamic State affiliate in Afghanistan. He hinted at further strikes against the group in retaliation for a deadly suicide bombing near Kabul's airport.

The US Central Command announced on Friday that US forces carried out a drone strike against the militant group ISIS-K. It is believed to have conducted the bombing on Thursday, in which many civilians and 13 US service members were killed.

In a statement issued on Saturday, Biden said, "This strike is not the last. We will continue to hunt down any person involved in that heinous attack and make them pay."

Biden noted, "The threat of terrorist attacks on the airport remains high. Our commanders informed me that an attack is highly likely in the next 24-36 hours."

He went on to say that he discussed with his national security team in Washington and his commanders in the field the ongoing preparations to help people continue to leave Afghanistan after their military departs.

Earlier on Friday, Defense Department Press Secretary John Kirby said at a briefing that the US drone strike killed two high-profile members of ISIS-K, a "planner" and a "facilitator," and injured another person.
