A suspected suicide bomb exploded outside Kabul airport on Thursday, killing at least 13 people including children, a Taliban official said, after the United States and allies urged Afghans to leave the area because of a threat by Islamic State, Reuters reported.
The official said many Taliban guards were wounded.
A U.S. official said U.S. service members were among the wounded, adding he was citing an initial report and cautioning that it could change. He said there were casualties but did not know how many or of what nationality.
Thousands of people have been gathering outside the airport in recent days. Western troops are racing to evacuate foreigners and Afghans who helped Western countries during the 20-year war against the Taliban, and to get out themselves by an Aug. 31 deadline.
A Pentagon spokesman confirmed an explosion near the Abbey Gate entrance to the airport had caused an unknown number of casualties. A Western diplomat in Kabul earlier said areas outside the airport gates were “incredibly crowded” again despite warnings of a potential attack.
Many U.S. officials said the blast appeared to be a suicide attack and a witness in Kabul saw many wounded men, women and children waiting for treatment outside a hospital.
Western countries have been warning of a threat by Islamic State militants.
The Taliban, whose fighters are guarding the perimeter outside the airport, are enemies of the Afghan affiliate of Islamic State, known as Islamic State Khorasan (ISIS-K), after an old name for the region.
“Our guards are also risking their lives at Kabul airport, they face a threat too from the Islamic State group,” said a Taliban official, who spoke on condition of anonymity and before the reports of the explosion.
U.S. President Joe Biden has been briefed on the explosion, according to a White House official. Biden was in a meeting with security officials about the situation in Afghanistan when the explosion was first reported, according to a person familiar with the matter.
The concerns about an attack came against a chaotic backdrop in Kabul, where the massive airlift of foreign nationals and their families as well as some Afghans has been under way since the day before the Taliban captured the city on Aug. 15, capping a lightning advance across the country as U.S. and allied troops withdrew.
Canadian forces halted their evacuations of around 3,700 Canadian and Afghan citizens on Thursday, saying they had stayed as long as they could before the deadline lapses. U.S. and allied troops also have to plan the logistics of their own withdrawal.
“We wish we could have stayed longer and rescued everyone,” the acting chief of Canada’s defence staff, General Wayne Eyre, told reporters.
