Casualties mount in Gaza-Israel violence

Two people have been injured, including one child, in the town of Beit Lahia in the Gaza Strip by a rocket fired from an Israeli drone, according to Palestinian medical sources.
Earlier on Sunday, rockets fired from Gaza fell in southern Israel in a continuation of days of cross-border air strikes and rocket attacks that have left at least 30 people dead.
At least 12 rockets landed on Sunday, but no serious injuries were reported, according to Israeli army officials.
An Israeli man was killed on Saturday by a rocket strike in the southern city of Beersheba, while Israeli air strikes on Gaza left a Palestinian man seriously wounded.
Israeli ministers held an emergency meeting on Saturday night to discuss the violence while the Arab League is expected to hold emergency talks on Sunday.
Israeli aerial attacks on Gaza have killed at least 15 people, among them gunmen and five civilians including three children, since gunmen killed eight people near the Red Sea resort of Eilat on Thursday. Israel blamed that attack on Palestinian fighters who had entered southern Israel from Gaza via Egypt.
The Israeli army's chief spokesperson, Yoav Mordechai, told Israel Radio on Sunday that Israeli forces would not "not hesitate to widen its actions and to respond with as much force as is needed".
Seven other people, including two children, were wounded by more than 50 rockets fired from Gaza on Saturday.
The Popular Resistance Committees (PRC) claimed responsibility for Saturday's deadly rocket strike in Beersheba. Hamas's armed wing claimed responsibility for another attack that destroyed a home in the town of Ofakim.
It was the first time in months that Hamas had declared its involvement in rocket attacks against Israel, after largely observing a de facto truce since the end of a three-week offensive in January 2009.
Al Jazeera's Cal Perry, reporting from Jerusalem, said that Israel held Hamas, which governs Gaza, responsible for the rocket attacks.
"Hamas has called off the ceasefire that was in place with Israel, largely due to the violence and the continued strikes that we see from Israeli aircraft, killing at least 15 Palestinians," our correspondent said.
"They do blame Hamas whenever anything originates from Gaza, be it a rocket attack from the south - we have seen 70 of those since Thursday - or an attack like we saw from southern Israel."
Akiva Eldar, cheif political commentator for the Israeli newspaper Haaretz told Al Jazeera: "I dont think that Hamas has any interest in this right now and I think they were doing everything to avoid taking the blame for undermining the diplomatic attempts."
World powers on Saturday expressed concern over the ongoing violence.
A statement in Brussels from the diplomatic quartet of the European Union, Russia, the United Nations and the United States said they remained "concerned about the unsustainable situation in Gaza as well as the risk of escalation, and calls for restraint from all sides."
