US carries out air strikes in Syria after American contractor killed

The US intelligence community assessed that the one-way attack drone was Iranian in origin, the military said, a conclusion that could further aggravate already strained tensions between Washington and Tehran.

The US military carried out multiple air strikes in Syria on Thursday night against Iran-aligned groups who it blamed for a deadly drone attack that killed an American contractor, injured another and wounded five US troops earlier in the day, the Pentagon said.
