GAZA CITY - Three Palestinians, one of them a 12-year-old boy, were killed by Israeli fire Friday as thousands of protesters gathered along Gaza's perimeter fence with Israel, health officials said.
The Gaza Health Ministry said at least 80 Palestinians were wounded by live fire and that six of them were in serious condition.
The Israeli military said about 13,000 protesters massed at several points along the fence, some burning tires and hurling rocks, grenades and firebombs. An Israeli officer suffered light wounds from pipe bomb shrapnel.
At night fall, two tank shells hit a watchtower that had been set up by Hamas, the Islamic militant group in control of Gaza. The tower was about half a mile from one of the protest camps near the fence, and protesters left in a hurry as they heard the thud of the shells.
The Israeli military said in statement that aircraft and a tank struck two Hamas positions in response to the explosives thrown at troops on the border.
