Italian authorities have evacuated 11 migrants from the Open Arms ship but not granted port access to the vessel, leaving it stranded in rough seas with 62 African migrants still on board, a spokeswoman for the Spanish rescue mission said on Sunday.

Among those evacuated are two young children and their families, several people suffering from burns and one man with a gunshot wound to his foot. They will be taken to the Italian port of Augusta.

The Open Arms picked up 73 migrants from a packed rubber dinghy drifting about 50 miles off Libya on Wednesday night and is seeking a safe harbor for those who remain on board.
