Activists who were planning to sail an aid ship to Gaza say it was struck by drones in international waters off the coast of Malta - appearing to accuse Israel of being behind the attack.
The Freedom Flotilla Coalition said its ship The Conscience was targeted at 00:23 local time on Friday and issued an SOS signal right after the attack.
The group said it had planned to sail to Gaza and "challenge Israel's illegal siege and blockade" there.
The Maltese government said everyone aboard the ship is "confirmed safe" and that a fire onboard the ship was "brought under control overnight".
