TEHRAN, April 2 (RIA Novosti) - Two U.S. Air Force bombers violated Iranian air space last week, a Tehran-based Arabic language news channel, Al-Alam, said Monday.

The channel, referring to a spokesman for Iran's Islamic Revolutionary Guards Corps, said two U.S. bombers crossed the Iranian-Iraqi border Saturday near the city of Abadan, in the province Khuzestan.

The spokesman said that it was not the first time military aircraft of the U.S. occupation forces in Iraq have violated Iran's air space, adding that Iranian President Mahmoud Ahmadinejad was on a working visit to the province of Khuzestan at the time of the incident.

The U.S. has not excluded a military option in the standoff with Iran over its refusal to abandon its uranium enrichment program. The UN Security Council passed a new resolution on Iran two weeks ago toughening economic sanctions against the country and accepting the possibility of a military solution to the crisis.

Tehran has consistently dismissed suspicions that it is running a covert nuclear weapons program, saying the country needs nuclear energy for civilian use.

Last week, a Russian security official said that Russian intelligence had information that the U.S. Armed Forces had nearly completed preparations for a possible military operation against Iran and would be ready to strike in early April.
