More than 120 bodies of migrants who died trying to cross the Mediterranean to Europe have washed up around Sabratha in western Libya this month, the city's mayor said on Sunday.

Hussein Thwadi said bodies had washed up on a daily basis, with 53 found on a single day last week.

Libya is a common departure point for migrants seeking to travel to Europe by boat, many of them fleeing violence, repression or poverty in sub-Saharan Africa.
