One of the boats engine failed while the other deflated. Those who survived, did it by clinging to floating wreckage, Reuters reported.
According to a survivor, rescuers from Europe arrived on scene with aircraft and threw life rafts, but migrants remained in the water for hours.
The vessels were carrying mainly people from African, while the survivors were brought to the Libyan port of Khoms on September 2 by the Libyan coastguard, where they faced more difficulties the MSF noted.
Namely, refugees and migrants were arrested and detained, without being protected or having legal recourse.
