Israeli forces attacked a group of Palestinians along the Gaza-Israel border early Tuesday, killing two gunmen and wounding three others in one of the worst flare-ups of violence since Israel ended its offensive in the territory more than two months ago, Associated Press reported. Palestinian witnesses reported hearing two explosions from the border area in the central Gaza Strip, after which Israeli helicopters hovered over the fence and fired at targets. Medical crews evacuated the bodies of two Palestinian men in military uniforms from the border, according to Dr. Moaiya Hassanain of Gaza's Health Ministry. Three other militants were wounded, Hassanain said, two in the initial clash and a third in a subsequent Israeli missile strike.
