The strike came just two days before the U.S. is set to conclude a massive airlift and withdraw the last of its troops, ending America’s longest war with the Taliban back in power.

The U.S. State Department released a statement signed by around 100 countries, as well as NATO and the European Union, saying they had received “assurances” from the Taliban that people with travel documents would still be able to leave.

The Taliban have said they will allow normal travel after the U.S. withdraws Tuesday.
