Three Palestinians were injured on Monday in two separate incidents in the Gaza Strip, local sources said, Xinhua reported.
A fisherman was wounded by Israeli fire off Gaza coast, while two youngsters were injured when playing with explosives apparently left by Israeli army.
Alam Baker, the fisherman, was moderately wounded off Gaza city coast when an Israeli gun vessel fired at his small boat, said Adham Abu Selmai, an emergency official.
Meanwhile, the media office of the Hamas-run Gaza police said that Mohammed Al-Za'aneen, 16, and his eight-year-old sister Asma were slightly injured "when a suspicious body from the Israeli leftovers" exploded near them in Beit Hanoun town in northern Gaza Strip.
Israel prevents the Palestinian fishing boats from sailing beyond two nautical miles, keeping them to work only in a space of 10 percent of the original fishing zone that was granted by Oslo peace accords in 1993.
Israel imposed a land and naval blockade on Gaza when Hamas movement took over the territory in 2007. But starting from last month, Israel has begun relaxing the closure due to international criticism of its policy following its deadly raid on a Turkish-led flotilla trying to break the siege.
