The five successive Israeli air and ground strikes came hours after militants from the Popular Front for the Liberation of Palestine (PFLP) fired two Russian-made Grad missiles on Thursday night from Gaza at southern Israel. The Popular Resistance Committees (PRC) had claimed responsibility earlier on Friday for launching four mortar Shells at Israeli army vehicles near the borders between southeast Gaza Strip and Israel. No injuries were reported. Israeli Radio reported earlier on Friday that two Grad rockets fired from the Gaza Strip landed on Thursday night at an opened area in the Negev in southern Israel causing no harms or casualties. Israeli Prime Minister Benjamin Netanyahu has threatened two days ago that the Israeli army would respond to every single rocket that militants from Gaza fire at Israel. The escalation of violence between Israel and Gaza militant had mounted as the Palestinians marked on Dec. 27 one year anniversary for launching a 22-day Israeli military offensive on the Gaza Strip that left more than 1,400 people killed.
