Gaza-Israel violence rages on

GAZA, April 9 (Reuters): Israel killed four Palestinian militants and wounded half a dozen others as it pursued air raids in Gaza for a third day on Saturday, responding to increased rocket fire out of the territory, local medics said.
Militants in the Gaza Strip, ruled by the Islamist Hamas, continued striking Israel's south with rockets, wounding five Israelis at around daybreak, according to Israeli media reports.
Israeli forces killed a local Hamas commander in the southern Gaza town of Rafah bordering Egypt, as well as two of his bodyguards, in a targeted strike on a vehicle, medics said. Israel blamed the slain commander for a rocket strike on its port of Eilat launched from Egyptian Sinai some months ago.
Five militants were wounded in a second air raid in northern Gaza. Another air strike at daybreak killed a further militant. Cross-border violence has surged since Hamas militants fired an anti-tank rocket at an Israeli school bus on Thursday, wounding two people including a teenager, who was listed in critical condition.
Israel has said it wants to teach Hamas a lesson for that attack, which Prime Minister Benjamin Netanyahu said on Friday amounted to "crossing a line," adding that "whoever tries to attack and murder children puts his life on the line."
At least 18 Palestinian militants and civilians, including an 11-year-old boy, have been killed in retaliatory strikes on the Gaza Strip since Thursday, and 36 since the latest round of bloodletting began in earnest on March 20.
Gaza militants have fired over 70 rockets and mortars into Israel since Thursday, damaging a house, police said. Israeli media said half a dozen people have been wounded. Some 50 rockets were fired on Friday, and Israel's "Iron Dome" missile defense system has intercepted seven since then.
Israeli security cabinet member Gideon Sa'ar said on Saturday that Israel's raids in Gaza, a tiny coastal territory under blockade by the Jewish state, would go on.
