Washington is increasing diplomatic pressure on Iran over alleged al-Qaeda operations in the Islamic republic.
The Washington Postreported the White House was set to consider tomorrow an effort to destabilise the Iranian government through a popular uprising.
White House spokesman Mr Scott McClellan told reporters: "The unelected few in Iran need to heed the wishes of the Iranian people", referring to the religious clerics who run the country.
The State Department last week told Iran to crack down on suspected al-Qaeda members operating in the country. The United States cancelled plans to meet Iranian officials in Geneva last Wednesday in protest.
Senator Pat Roberts, the Republican chairman of the US Senate Intelligence Committee, and other lawmakers said some positive development related to Iran was expected soon.
Mr Roberts indicated it was related to US charges that al-Qaeda leaders were operating out of Iran and possibly linked to the recent suicide bombings in Saudi Arabia.
US officials claim two of Osama bin Laden's sons - Adel and Saad bin Laden - are believed to be in Iran. The United States severed ties with Iran after the 1979 Islamic revolution.
Iran's ambassador to the United Nations told ABC's This Weekprogramme his country had arrested several members of al-Qaeda but had not yet identified them. He also said his country would be willing to turn them over to "friendly governments," such as Saudi Arabia.
