At least 90 migrants are feared to have drowned off the coast of Libya after a smuggler’s boat capsized early on Friday, the UN’s migration agency has said. Survivors told aid workers that most of the migrants on board were Pakistanis, who form a growing group heading to Italy from North Africa, a spokeswoman for International Organisation for Migration, said. “They have given an estimate of 90 people who drowned during the capsize, but we still need to verify the exact number of people who lost their lives during the tragedy,” Headon, speaking from Tunis, told a Geneva news briefing. “What has been reported to us is that it’s mostly Pakistanis who were on board the boat, but we still need to verify the nationalities and how many from what country,” she said. Ten bodies have so far washed ashore near the Libyan town of Zuwara, two of them known to be Libyans and eight Pakistanis, she said. “I believe the Libyan coastguard is looking for other survivors off the coast,” Headon added. Earlier security officials in the western Libyan town of Zuwara said two Libyans and one Pakistani had been rescued from the boat. They said 10 bodies had been recovered, mostly Pakistani, but gave no further information. Zuwara, located near Libya’s border with Tunisia, was a favored site for migrant boat departures over the past two years but of late has seen only occasional departures. A statement from the Zuwara coastguard said their initial information suggested there were some 90 people on board. Libya is the main gateway for migrants trying to cross to Europe by sea, though numbers have dropped sharply since July as Libyan factions and authorities - under pressure from Italy and the European Union - have begun to block departures. More than 600,000 people are believed to have made the journey from Libya to Italy over the past four years. Prior to Friday’s incident, some 6,624 migrants are believed to have arrived in Europe by sea so far this year and a further 246 have died, according to IOM figures.
