Activists taking part in a flotilla seeking to break the Israeli blockade of Gaza said on Wednesday that some of their boats were attacked by drones overnight while sailing south of Greece. The Global Sumud Flotilla said it was attacked during the night by “unidentified drones and communications jamming”.

It said that “at least 13 explosions” were heard on and around several flotilla boats, while drones or aircraft dropped “unidentified objects” on at least 10 boats. No casualties were reported but there was damage to the vessels and widespread obstruction in communications, it added.
