Netanyahu Defends Israeli Offensive in Gaza on US Television

Netanyahu appealed for sympathy for Israelis under siege from militant rockets as a warning siren followed by an all-clear signal punctuated his interview on CBS' "Face the Nation."

"When we began this interview we were under bomb alert and as the minutes passed now we're told people can go out into the open air again," he said.

"This is the kind of reality we're living in. And we'll do whatever is necessary to put an end to it," he said, referring to the escalating violence between Israel and Hamas, the Islamist movement that rules Gaza.

Netanyahu urged Americans to imagine that U.S. cities from the East Coast to Colorado, or 80 percent of the population, were under threat of rocket attack, with only 60 to 90 seconds to reach a bomb shelter. "That's what we're experiencing right now, as we speak," he said.

Netanyahu's television appearances came as thousands of Palestinians fled their homes in a Gaza town after Israel warned them to leave before threatened attacks on rocket-launching sites.

Sunday marked the sixth day of an offensive that Palestinian officials said has killed at least 160 people.

Militants in the Gaza Strip kept up rockets salvoes deep into the Jewish state and the worst bout of Israel-Palestinian bloodshed in two years showed no signs of abating as Western foreign ministers meeting in Vienna said a ceasefire was an urgent priority.

Netanyahu refused to discuss a ceasefire or give a timeline for Israel's operation in Gaza.

Asked if a ground invasion was imminent, he said Israel would use any means necessary to accomplish its goal of degrading Hamas's rocket-launching capability to restore security for Israeli civilians.

"Whether we're at the beginning of the end or the end of the beginning I'm not going to tell you that right now - because we face a very, very brutal terrorist enemy," he said on "Fox News Sunday."

As international pressure built for restraint, Netanyahu said he had spoken with U.S. President Barack Obama and other world leaders who understood Israel's need to defend itself.

"We'll do what is necessary," he said. "What any country would do: What the United States would do, what Britain would do, what France would do, and many, many other countries."
