Britain's foreign minister Dominic Raab said he spoke with Secretary of State Antony Blinken on Thursday to express sympathy for the US troops killed after suspected suicide bombers struck the crowded gates of Kabul airport.
"They paid the ultimate sacrifice while helping others reach safety," Raab said in a statement. "I also want to extend my condolences to the families of all those Afghans killed or injured. It is tragic that as they sought safety they have suffered at the hands of terrorists."
Over 70 casualties have been reported from the attack at Kabul airport, with reports of 12 US troops killed in the bombings.
