Palestinians watch rescue workers as they search for the bodies of three Hamas militants inside a tunnel targeted by an Israeli air strike, near the border between Israel and Khan Younis in the southern Gaza Strip, on November 2, 2013. The Israeli air strike killed the three militants in the Gaza Strip the day before, the Islamist group Hamas said, while the Israeli army said five of its soldiers were wounded by an explosive device. The Israeli military said the fighting erupted when an explosive device went off as troops were clearing a tunnel from the Gaza Strip into Israel, allegedly to be used as a springboard for militant attacks.
