An Israeli youth stands next to a house that was damaged after a rocket fired by Palestinian militants from the Gaza Strip, landed in the southern Israeli town of Beersheba, Wednesday, March. 23, 2011. Gaza militants say they've fired rockets at Israel after the Israeli military killed seven Palestinians, including three children and their uncle. The first rocket landed near the coastal city of Ashdod, and the Israeli military said it carried out a retaliatory airstrike early Wednesday. No Israeli injuries were reported in the rocket attack, but Palestinians say one militant was killed in the airstrike. Hours later, a rocket struck southern Israel's largest city, Beersheba, moderately wounding one person. Islamic Jihad claimed responsibility for both rocket attacks. The killing of the civilians Tuesday dramatically escalated a recent round of simmering violence. Israel says a mortar strike targeting militants went astray.(AP Photo/Oded Balilty)
