"A rubber boat capsized off Misurata coast carrying 25 illegal immigrants. 15 migrants drowned, while 10 others survived after reaching Misurata shore," Baha al-Kawash, Libyan Red Crescent spokesman told Xinhua later Tuesday.
Othman Belbeisi, chief of the International Organization for Migration (IOM) mission in Libya, said the 10 migrants suffered severe dehydration.
"Only 10 survivors suffering from severe dehydration taken to detention center, IOM Libya doctors and emergency team on the way. Alarming we still do not see solid steps to address irregular unsafe movements across MedSea (Mediterranean Sea)," Belbeisi said on his Twitter account.
Thousands of illegal immigrants choose to cross the Mediterranean from Libya to Europe, due to the state of insecurity and chaos in the north African nation since the fall of the late leader Muammar Gaddafi's government in 2011.
