Israeli security forces secure the area after an attack, near the southern Israeli city of Beersheva, Monday, June 18, 2012. Unidentified militants crossed from Egypt's turbulent Sinai Peninsula into southern Israel on Monday, opening light arms and anti-tank fire on civilians building a security fence meant to fortify the porous border, defense officials said. One of the Israeli workers was killed, and two militants were gunned down by troops responding to the attack, the officials said. (AP Photo/Tsafrir Abayov)
