Libya, following the toppling of leader Muammar Gaddafi in a NATO-backed uprising in 2011, has become a transit route for migrants fleeing conflict and poverty to Europe via the dangerous route across the desert and over the Mediterranean.

Four bodies were recovered on Thursday morning and two more on Thursday evening, said Makhlouf Karim, head of the rescue department in Misrata’s Red Crescent branch.

In February, Libyan security authorities recovered dozens of bodies from mass graves in two different locations in the country’s southeast region. The country’s oil-based economy is also a draw for migrants seeking work.
