The US military says it's carried out a drone strike against an Islamic State "planner", a day after 13 American soldiers were killed in a bomb attack near Kabul airport.
Offshoot ISIS-K says it was responsible for the blast, which also killed two British nationals and the child of another Briton.
Conflicting reports say nearly 170 Afghans died.
This man in Kabul says he was caught up in the chaos with his children.
