AlQa'dah 18, 1435, Sep 13, 2014, SPA -- Corpses have been found at sea after a boat carrying some 30 migrants sank south of Malta, officials said Saturday, according to dpa. Two children were among seven survivors of the shipwreck some 300 nautical miles (550 kilometers) off the Mediterranean island, the army said. The survivors were rescued by merchant vessels operating in the area on Friday afternoon. Malta's rescue coordination centre launched a search mission involving several cargo ships, three Italian coast guard vessels, three Italian and one Maltese aircraft. Some of those rescued needed urgent medical care.
