Israeli warplanes Friday pounded targets across Gaza, killing at least five Palestinians, and militants fired dozens of rockets into Israel after attempts to extend a three-day truce stalled.

The month-long conflict flared once again after mediators tried but failed to extend a ceasefire that expired at 0500 GMT as Palestinian militants shattered the quiet with pre-dawn rocket attacks.

Cradling his baby daughter, Saeed Masri took flight Friday from renewed Israeli bombardment of Gaza with little faith that even a U.N. facility can protect his family.

Three hours after a temporary ceasefire between Israel and Hamas ended, a missile hit the roof of a building opposite the apartment in Jabaliya where he was staying with relatives after his own neighborhood was shelled.

Speaker Nabih Berri has urged the Lebanese authorities to deal with the Syrian encampments “differently” after many gunmen taking refuge there joined militants last weekend and took over the northeastern border town of Arsal.

“From now on, we should deal with the refugee encampments differently and not to tolerate” the presence of armed men there, Berri was quoted as saying by several newspapers that hit the newsstands on Friday.

The vast majority of rockets fired by Hamas at Israel over the past month were made in Gaza using civilian materials, a senior Israeli military official said Thursday.

The coastal Palestinian enclave was the setting for the 28-day conflict with Israel, during which Israel set out to seriously impair the Islamist movement's military abilities.

A spokesman for Hamas's armed wing, the Ezzedine al-Qassam Brigades, warned Thursday of renewed fighting with Israel if talks in Cairo to extend a 72-truce in Gaza collapsed.

"We appeal to the Palestinian delegation to not accept a ceasefire, unless it satisfies the demands of our people," a spokesman using the nom-de-guerre Abu Obeida said in a televised address, adding that Hamas fighters were "ready to return to battle."

The scale of civilian losses during the four-week conflict in the Gaza Strip must not happen again, the head of the International Committee of the Red Cross said on Thursday.

Speaking to reporters after visiting Gaza, ICRC President Peter Maurer said he was "deeply distressed and shocked to see the impact of violence on the civilian population".

British aid agencies launched an emergency appeal on Thursday for people affected by the conflict in Gaza, with the BBC agreeing to show adverts calling for donations -- five years after it refused to participate in a similar drive.

The Disasters Emergency Committee (DEC), which brings together 13 leading British charities at times of crisis, said half a million people in Gaza have been forced from their homes, and that up to 1.5 million have limited access to water, sanitation or medical care.

Hundreds of Palestinians poured onto the streets of Gaza City on Thursday to attend a Hamas victory rally, chanting support for resistance against Israel, an AFP reporter said.

Loudspeakers mounted by the roadside blared out Hamas victory songs as the crowd -- most of them men but with some children dressed in combat fatigues and carrying toy guns -- gathered in the square outside the parliament building.

Israeli Foreign Minister Avigdor Lieberman has called for EU "inspectors" to monitor Gaza's borders amid efforts to extend a ceasefire, in a German newspaper interview published Thursday.

U.S. President Barack Obama said Wednesday that the people of Gaza need greater hope for the future, as he urged the extension of an Israel-Hamas ceasefire.
