CAIRO (AP) — Libya’s coast guard fired upon a vessel belonging to a humanitarian group as it searched for a migrant boat in distress in the Mediterranean Sea, the nonprofit said on Monday.

The attack, which took place the day before, appeared to be one of the most violent involving a European rescue ship and the Libyan coast guard, which receives training, equipment and funding from the European Union.

SOS Mediterranee said the confrontation took place about 40 nautical miles north of the Libyan coast, and released details and images of the incident. No casualties were reported, although the group said the vessel sustained significant damage.
