Tel Aviv (AFP) - Thousands of Israelis rallied Saturday for fresh Israeli-Palestinian peace talks, on the eve of the 20th anniversary of the killing of prime minister Yitzhak Rabin.

The demonstrators chanted "Jews and Arabs don't want to hate each other" and "Israel, Palestine, two states for two peoples" as they came together amid a new upswing in violence which makes prospects for peace in the decades-old conflict look deeply gloomy.

They gathered at Tel Aviv's Rabin Square, the site where the Nobel peace laureate was gunned down by a rightwing Jewish extremist at the age of 73 on November 4, 1995.

Activist group Peace Now -- which organised the rally along with the left-wing Meretz party and others -- estimated there were some 6,000 people attending.

Daniel Dojon told AFP he came "because the situation is crazy. I am not talking about safety but the lack of (political) progress, the lack of hope. Israeli politicians are becoming more and more extreme."

Another protester, who identified himself only as Zeev, 67, blamed the lack of a peace process for the current violence.

"It will further deteriorate if we think that being passive is the answer."

Dov Kredo, 60, who attended the peace rally where Rabin was killed, came from Galilee in northern Israel, and said he feels "very pessimistic" about the current situation.

"It is much easier for people to answer the call of fear and hatred," he said.

- State memorial -

Rabin's killer, Yigal Amir, had hoped to derail the 1993 Oslo accords signed by Rabin and the Palestinians, a landmark agreement aimed at resolving the decades-old conflict.

He is currently serving a life sentence.

According to the Hebrew calendar the anniversary falls now, rather than in November.

On Sunday President Reuven Rivlin hosts a candle-lighting tribute in Rabin's memory and on Monday there will be a state memorial ceremony alongside his grave in the national cemetery on Jerusalem's Mount Herzl.

"The path that was stopped in 1995 is very much the path that needs to be taken today," Peace Now spokeswoman Anat Ben Nun told AFP.

Israeli-Palestinians tensions, always simmering, have surged recently in a wave of Palestinian knife and gun attacks, as well as clashes between Palestinians and Israeli security forces.

Since the start of this month, 52 Palestinians and one Israeli Arab have died in clashes or while carrying out attacks.

Eight Israelis have died in attacks. One Israeli Jew and one Eritrean have been killed after being mistaken for attackers.

"What we see now is very much related to the path not taken since 1995," Ben Nun said, adding that Saturday night's protest was aimed at the policies of the incumbent right-wing government of Prime Minister Benjamin Netanyahu.

The most recent attempt to resolve the conflict collapsed in April 2014 amid bitter recriminations on both sides.
