TEHRAN, Feb. 11 (Xinhua) -- Iranian president on Sunday said that regional states, including Iran, have aborted U.S. plots over the past year.

"The plots by the United States and Israel to create division among the Iranians, Iraqis and the Lebanese were defeated," Hassan Rouhani said here, addressing a huge gathering to celebrate the 39th anniversary of the victory of the Islamic revolution.

"The Americans wanted to interfere in our internal affairs, but our people turned back to them," Rouhani said, alluding to the recent unrests in the cities of Iran over the economic hardship of people.

The Iranians in solidarity and unity aborted all the U.S. plots and plans to disturb the country, he added.

Hundreds of thousands of Iranians attended nationwide rallies on Sunday to celebrate the 39th anniversary of the victory of the Islamic revolution in 1979.

People in the Iranian cities swarmed to the streets, chanting anti-U.S., anti-Israeli slogans and carrying images of the late founder of the Islamic republic, Ayatollah Seyed Ruhollah Musavi Khomeini, and his successor, the incumbent leader Ayatollah Ali Khamenei.

Earlier, Khamenei and Rouhani called for mass turnout in the rallies to condemn the U.S. recent threats against the Islamic republic.

The 1979 revolution in Iran toppled the U.S.-backed regime of Shah and brought the country under the leadership of Khomeini, an event seen as a turning point in Iran's history.
