Around 290 migrants, including 14 Bangladeshis, have been rescued by the Libyan Navy.
The Europe-bound migrants in three boats were rescued off the country’s Mediterranean coast on Friday, reports Washington Post.
The western coast of Libya is the main departure point of hundreds of thousands of migrants fleeing their countries from wars and poverty to reach shores of Italy.
Libyan coast guards first reported finding a sinking rubber boat whose bottom had collapsed on Thursday, leaving most migrants in the water and hanging onto what was left of the boat and plastic barrels.
A statement posted on Friday on the navy press center’s official Facebook page says that boat carried 87 migrants, including six women and a child.
Earlier, the coast guard came to the rescue of two other rubber boats carrying a total of 203 migrants, according to a separate statement.
The three boats carried mostly Arab and African nationals as well as 14 Bangladeshis, who were handed over to Libyan police after receiving humanitarian and medical aid.
A few hours earlier, German aid group Sea-Watch said its aircraft had witnessed three rescue operations by Libyan coast guards on Thursday.
