A Palestinian rocket attack killed an Israeli man on Sunday, the second Israeli victim in a nearly two week-long rocket barrage.
Hamas claimed responsibility for the rocket attack, which also wounded another Israeli in the town of Sderot.
Israeli Prime Minister Ehud Olmert warned again that no one involved in terror is immune from Israeli air strikes aimed at stopping the rocket attacks.
The Israeli air campaign against Hamas militants has killed nearly 50 Palestinians -- mostly militants, over the past ten days.
A spokesman for moderate Palestinian President Mahmoud Abbas says he is working to secure a ceasefire to end the violence.
Israeli airstrikes overnight Saturday in Gaza hit security posts of the militant group, Hamas. Earlier Israeli airstrikes Saturday killed at least five Hamas militants and wounded 10 others.
Israel's army says the Palestinians have fired at least 220 rockets since May 15th.
