Occuppied Jerusalem: Israel on Wednesday postponed a decision on whether to order its armed forces to storm the Gaza Strip's urban centres, an Israeli official said, citing Egyptian- and French-led efforts to secure a truce with Hamas.

Israel called the initial ground sweep the "second stage" of an operation to counter cross-border Palestinian rocket salvoes, without giving details on what might follow.

Prime Minister Ehud Olmert's security cabinet, convening on Wednesday, discussed the third and final stage of the offensive but deferred voting on the plan to an undisclosed date.

"The plan is to enter the urban centres," an official said before the deliberations.

Postponing a final decision on the plan allowed Israel to keep its forces in readiness while maintaining leeway for any breakthrough in the Egyptian- and French-led ceasefire talks.

Asked about the deferral, a senior Israeli defence official said: "We are pursuing parallel military and diplomatic tracks, so this is no simple matter."
