Jerusalem • The Palestinian president has set off a strident debate by shattering a once-inviolable taboo, publicly suggesting his people would have to relinquish claims to ancestral homes in Israel.

Mahmoud Abbas' comments on the refugee issue, made in an interview on Israeli TV over the weekend, triggered hot responses from Palestinians and Israelis alike.

In Israel, it suddenly put the long-sidelined issue of peace talks back in the Israeli public's consciousness ahead of parliamentary elections.

Palestinians have maintained for six decades that Arabs who either fled or were expelled from their homes during the fighting that followed Israel's 1948 creation, and all their descendants, have the right to reclaim former properties in what is now Israel.

Israel says a mass return of these people, believed to number 5 million, would spell the end of Israel as the Jewish state. Also, Israel rejects the concept of a legal "right of return."

In the interview, Abbas was asked about his birthplace of Safed — now a town in northern Israel. He told the interviewer that while he would like to visit, he doesn't claim the right to live there.

"I am a refugee, but I am living in Ramallah [in the West Bank]. I believe that the West Bank and Gaza is Palestine. And the other parts is Israel," Abbas said in English. "I want to see Safed. It is my right to see it, but not to live there," he said.

The comments were widely seen as an acknowledgment that return of all the refugees would be impossible. While Palestinian officials privately acknowledge that, they have been reluctant to say so in public.

His adviser, Nimr Hammad, said Abbas was being "realistic."

"He knows he can't bring back 5.5 million Palestinian refugees to Israel," Hammad said.

Some West Bank Palestinians were disappointed that their leader had made an overture to Israel without receiving any gestures in exchange.

"President Abbas is a failure," said Iyad Alotol, a government employee in Ramallah. "He is ceding the right of return without getting anything from the Israelis."
