More than 80 people trying to reach Europe from Libya are feared dead after their boat capsized off the coast of Tunisia, according to the UN migration agency.

The boat sank on Wednesday off the port town of Zarzis and 82 of the migrants who had been onboard were missing, the International Organization for Migration (IOM) said. Fishermen pulled four men from the sinking boat, said Lorena Lando, the agency's head in Tunisia. One of the four died later in hospital.
