According to Safa Msehli, a spokeswoman for the International Organization for Migration, the Libyan coast guard, which receives funds from the European Union, intercepted more than 24,000 Europe-bound migrants in the Mediterranean so far this year, including over 800 this week alone.
However, only 6,000 have been accounted for in official detention centers in the North African country, she said. The fate and whereabouts of thousands of other migrants remain unknown.
Traffickers have exploited the chaos and often pack desperate families into ill-equipped rubber or wooden boats that stall and founder along the perilous Central Mediterranean route. Thousands have drowned along the way. They have been implicated in widespread abuses of migrants, including torture and abduction for ransom.
