SIDON, Lebanon: Israeli jets dropped flare bombs along the coast of the southern city of Tyre Monday, security sources told The Daily Star.

The aircraft launched five flares to illuminate the night sky for reconnaissance purposes, the sources said, adding that the devices extinguished five to 10 minutes after they were released.

Earlier Monday, the Lebanese Army said four Israeli warplanes violated Lebanon’s airspace and flew over various areas.

Two of the planes entered the country at 6 a.m, the military said in a statement. The jets conducted aerial maneuvers over several regions, leaving the area three hours later, it added.

Immediately following the departure of the planes, two other aircraft entered Lebanese airspace and conducted similar maneuvers, leaving at 12 p.m, the Army said.

Israel violates Lebanon’s airspace on near daily basis, in violation of United Nations Security Council Resolution 1701.
