Tel Aviv - Israeli Foreign Minister Tzipi Livni will travel to Paris Thursday to debate the crisis in Gaza with French President Nicolas Sarkozy and Prime Minister Francois Fillon, a senior adviser said.

The adviser, Yigal Palmor, said they would discuss "different ideas about what can be done on the diplomatic level" - but not a French proposal for a 48-hour humanitarian truce in Gaza, which Israel has rejected.

"She is going to take with her facts and arguments to try to explain what our policy is," he said, adding "also their opinion will be heard."

The official told Deutsche Presse-Agentur dpa that Israel rejected the French initiative for a 48-hour truce because it was seeking a durable solution to the rocket and mortar attacks from Gaza which would restore security and normal life to civilian residents of southern Israel.

"This 48-hour initiative was not considered as something useful because it's only 48 hours," he said, adding that "to call it a humanitarian truce for 48 hours, that's also not necessary because the border crossings are open permanently for all aid."

While before the five-day-old offensive Israel had reduced aid shipments to Gaza to about once a week amid ongoing rocket attacks, the Israeli government had now given the "clear instruction" to the Israeli military to allow in unrestricted aid.

Since the offensive, which has proved the deadliest in decades of Israeli-Palestinian fighting, started Saturday, several dozen trucks with supplies including food and medicine have entered each day. (dpa)
