TRIPOLI, Feb. 2 (Xinhua) -- Libyan navy on Friday questioned the validity of reports about a capsizing boat carrying 90 illegal immigrants off the coast of the city of Zuwara, some 120 km west of Tripoli, according to navy spokesman Ayob Qassem.

"The reports published by international organizations about a capsizing boat with 90 illegal immigrants on board off the city of Zuwara are uncertain and questionable because they are not based accurate evidence or sources," Qassem told Xinhua.

The international Organization for Migration announced earlier on Friday that nearly 90 immigrants were feared drowned off Zuwara coast, and that three immigrants survived and made it to the shore alive.
