US forces have launched a 'defensive' military strike in Kabul against a vehicle carrying 'multiple suicide bombers' from the Islamic State’s local affiliate in Afghanistan who were aiming to attack the airport, American officials have said. There was no immediate word on casualties and few other details about the incident, which may have triggered a second blast in a nearby house. Witnesses reported an explosion near Kabul airport and television footage showed black smoke rising into the sky. Taliban officials confirmed the US account. According to some reports, a child died in the second blast.
