Lebanese Army Command announced, in a tweet on Monday, that the search for the missing boat that capsized off Tripoli in April had been postponed due to high sea waves that might threaten the safety of the submarine and its crew.

Nearly three months after the deadly sinking of a boat carrying migrants off Qalamoun in Northern Lebanon, the Lebanese Army began a submarine search operation Monday off the coast of Tripoli to extract the bodies of some 30 people who are believed to still be trapped in the boat.

The boat sank to a depth of about 400 meters.

Nearly 85 passengers boarded a smuggler boat last April, heading for Europe, to escape the economic crisis in Lebanon. The ship was intercepted by the army about 5.5 kilometers off the Lebanese coast, but there are two conflicting versions as to the cause of the sinking. The army claims that the boat sank because of the overload of passengers on board.

The survivors, on the other hand, claim that the military boat purposely collided with the boat. Among the passengers, about 40 people are believed to have died, among those whose bodies were recovered and those still missing.
