A senior Iranian official said Monday Iran does not trust the United States due to its contradicted stances.

Ali Akbar Velayati, senior advisor to Iran's Supreme Leader Ali Khamenei for international affairs, made the remarks at a press conference held after his meeting with the Syrian Vice-President Farouk al Shara at the Iranian Embassy in Damascus.

"The Americans have exerted all efforts to snatch UN Security Council's resolution against Iran," he said.

UN Security council adopted last June a resolution on the Iranian nuclear issue, prohibiting Iran from investing abroad in nuclear and enrichment operations, imposing new restrictions on Iran's import of conventional arms and allowing the Iranian ships in the international waters to be checked.

Velayati stressed that U.S., EU and UN's sanctions have no impact on Iranian persistence to possess nuclear energy for peaceful use.

"We are confident that the Americans will depart the region in the near future," he noted.

He also confirmed that there is no difference between the Iranian and Syrian stances on the forming of a national Iraqi government.

"Iran and Syria respect any decision taken by the Iraqi people on his own interior issues," Velayati said.

Velayati hailed the Lebanese when facing of the Israeli violation at the Lebanese-Israeli borders.

A deadly skirmish erupted on Tuesday between Israeli army and Lebanese forces, resulted in four Lebanese soldiers and journalists killed and five other wounded, while one Israeli officer was killed.

The senior Iranian official held on Sunday a meeting with leaders of Hamas and Islamic Jihad (Holy War), as they exchanged views over regional affairs.

During the Syrian-Iranian Higher Committee meetings held in Damascus last April, Syria and Iran signed a memo of understanding on transport, communication, technology and economic cooperation.
