Israeli President Shimon Peres applauded Iran's pro-reform protesters on Sunday, saying the young should "raise their voice for freedom", while Prime Minister Benjamin Netanyahu said the world was sympathetic to Iranian election protesters but added it was unclear whether the unrest would spur change in Tehran's policies. Peres suggested the protesters could bring down their leaders. "Let the young people raise their voice for freedom, let the Iranian women ... voice their thirst for equality," Peres told a gathering of world Jewish leaders. If the protests continue, Peres said, "hopefully the poor government will disappear". "I have no doubt everybody in the world is sympathetic to the Iranians' desire for freedom," Netanyahu said on NBC's 'Meet the Press' when asked about the street demonstrations that have erupted in Iran since the disputed June 12 election. "I think it's too early to say what will transpire in Iran and on the international stage," said Netanyahu, who spoke from Israel. He reiterated Israel's position that Iran must not be allowed to develop nuclear weapons.
