JERUSALEM, Jan. 1 (Xinhua) -- Israeli Prime Minister Benjamin Netanyahu rejected on Monday comments by Iran's President Hassan Rouhani who blamed Israel for standing behind the protests in Iran.

Netanyahu's remarks followed comments by Rouhani on Sunday, who accused the United States and its two close allies, Israel and Saudi Arabia, of fueling the recent unrest in Iran.

In a video footage posted on his official Facebook account, Netanyahu praised the Iranian people for taking to the streets to protest against the regime. However, he said that the accusations of Israeli involvement were "not only false; it's laughable."

The hawkish Israeli leader went on to slam Europe for not supporting the demonstrators and avoiding from a stance against the Iranian political leadership.

"Sadly, many European governments watch in silence as heroic young Iranians are beaten in the streets," Netanyahu said. "That's just not right," he added.

Speaking to Iranian lawmakers, Rouhani played down the protest as "nothing," according to the Iranian news agency, Fars.

He blamed U.S., Israel, and Saudi Arabia for involvement in the unrest in order to destabilize the country.

Iran's "unity was a bullet (arrow) in their eyes and our progress and success in the world of politics and against the U.S. and the Zionist regime was not bearable to them," he said, adding that the Saudis "have blatantly said that we will create problems in Tehran."

Commenting on U.S. President Donald Trump support for the protest, Rouhani accused him of deception. "The guy who is totally against the Iranian nation has no right to sympathize with Iranians," Rouhani said.

At least 15 people have been killed in rallies across Iran in protest against the regime, according to Iranian media.
