Israeli naval forces opened heavy machinegun fire at Palestinian fishing boats off Gaza shores on Friday evening.
Local sources affirmed that the Israeli war boats fired heavy machineguns at Palestinian boats sailing off Gaza southern shores.
Palestinian fishermen were forced to leave the sea following the attack.
Israeli naval forces and their gunboats are around Gaza fishermen almost every day, harassing them, shooting at them, damaging their boats, and making arrests. Sometimes fishermen are injured or killed during gunfire attacks.
Under the 1993 Oslo accords, Palestinian fishermen are permitted to fish up to 20 nautical miles off the coast of Gaza, but since then Israel has kept reducing the fishing area gradually to a limit between six and three nautical miles as part of its blockade on Gaza.
Fishermen and human rights groups also say that since the 2008-09 war in Gaza, the Israeli army has been regularly enforcing a limit even closer to the shore.
