Boat carrying 86 refugees capsizes in Tunisia

A boat carrying at least 86 refugees and migrants has capsized off the coast of Tunisia, with most feared drowned.
According to some of the four initial survivors, the boat sank off the town of Zarzis.
Tunisian fishermen came across the sinking boat and were able to pull four survivors out but could not find any of the other passengers.
Eighty-two people remain missing in the incident, which comes a day after a deadly air attack on a Libyan detention centre killed at least 44 migrants.
