Israel's prime minister and the Palestinian president, in France for the climate summit, met and shook hands for the first time in years.
A photograph shows Benjamin Netanyahu and Mahmoud Abbas shaking hands and smiling on the sidelines of global climate talks outside Paris on Monday. It wasn't immediately clear if they had agreed to meet or if they spoke.
U.S. mediated peace talks between the sides collapsed early 2014 and the two leaders haven't met in years.
Their meeting came amid heightened tensions between Israelis and Palestinians. Over the past 2 months, almost daily Palestinian attacks have killed 19 Israelis while at least 97 Palestinians have been killed, including 62 said by Israel to be attackers. The rest died in clashes.
