WASHINGTON (Reuters) - Israeli Prime Minister Benjamin Netanyahu rebuffed international calls for a ceasefire while defending his country's offensive in Gaza during appearances on U.S. television on Sunday.
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 afterIsrael 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 Viennasaid a ceasefire was an urgent priority.
Netanyahu refused to discuss a ceasefire or give a timeline for Israel's operation in Gaza.
CALLS FOR RESTRAINT
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 Obamaand 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."
Former U.S. Middle East peace envoy Martin Indyk said he did not think Netanyahu wanted a ground war inGaza. "What he wants is an end to the rocket fire, and he's looking for ways to pressure Hamas to do that," Indyk said on NBC's "Meet the Press."
"But he's a very cautious man when it comes to using force and I think he's very reluctant to go in. And in a senseHamas knows that," said Indyk, a former U.S. ambassador to Israel. "So the bluff of mobilizing all of these tanks is not working in terms of getting Hamas to stop the firing."
Secretary of State John Kerry spoke with Netanyahu by telephone, telling him the United States was prepared to broker a ceasefire, a senior State Department official said.
U.S.-led peace talks between Israel and the Palestinians collapsed in April. Indyk, who stepped down shortly afterward, said Washington should continue to press for a ceasefire.
"The problem is how do you get Hamas to agree to a ceasefire," he said.
