Israeli Prime Minister Ehud Olmert has warned there could be stronger military action in the Gaza Strip if Hamas fails to stop its rocket attacks on southern Israel.
In broadcast remarks to his Cabinet Sunday, Mr. Olmert said, if the political and military steps Israel is taking do not bring about calm, Israel will be forced to intensify its response.
Israel has been pounding militant targets in Gaza since Tuesday in response to Hamas rocket attacks on its territory.
An Israeli air strike on a car in Gaza Sunday killed three suspected Hamas militants. A second strike hit a suspected weapons workshop.
On Saturday, four Palestinians were killed in Israeli air strikes against Hamas.
Meanwhile, the latest ceasefire agreed to Saturday by rival Palestinian factions appeared to be holding.
Under Egyptian mediation, Hamas and Fatah agreed to pull their fighters from the streets, remove road blocks and release hostages.
Previous ceasefires quickly collapsed, threatening to bring down the fragile unity government of the two factions.
