Reports say two of the rockets were intercepted by the Israeli Iron Dome missile system, but the rest passed through the US-sponsored system, with two of them hitting the central part of the southern city of Sderot, causing material damage and power cuts in most of Sderot neighborhoods.
The Israeli Air Force bombed dozens of sites in the Gaza Strip hours after a search for three missing young Israelis led to discovery of their dead bodies.
The airstrikes on 34 targets were conducted on Tuesday morning. The tension has been reaching the boiling point amid two weeks of door-to-door searches and arrests in the Palestinian territories by the Israeli forces.
