Gaza's Health Ministry says a 17-year-old Palestinian was killed by Israeli fire during a protest along the perimeter fence with Israel.
The ministry said Montaser al-Baz was shot in the head Tuesday and died hours later at a hospital.
The Israeli military said 200 protesters burned tires and threw explosive devices toward the fence. It said Israeli troops opened fire at one protester who approached the fence and lobbed an explosive device.
Hamas has held weekly protests along the frontier for six months, aimed at easing a crippling Israeli-Egyptian blockade. Recently, Hamas has appeared to be scaling back the protests amid renewed Egyptian efforts to broker a cease-fire with Israel.
Israeli fire has killed 157 Palestinians during the protests. An Israeli soldier was shot dead in July.
