Jeruaslem ? Prime Minister Ehud Olmert said Sunday he authorized the army to do whatever it takes to halt Palestinian rocket fire – even as an Israeli was killed by a salvo from Gaza – but warned his Cabinet there was no quick solution.

An 11-day campaign of Israeli airstrikes aimed at halting the rocket attacks from Gaza has killed 49 Palestinians, mostly militants. Hamas said the attacks would continue as long as the Israeli airstrikes persist.

A rocket slammed into the town of Sderot – one of nine the Israeli army said struck the area on Sunday – killing a 36-year-old computer technician as he was driving. It was the second time in a week a Palestinian rocket has killed an Israeli there.

“We need to be prepared for dealing with this in the long term,” Olmert warned his Cabinet. He said Israel’s campaign against the attacks would not be time-limited, nor would the country yield to outside pressure.
