TEHRAN, Jan. 20 (Xinhua) -- An Iranian lawmaker warned here on Tuesday of the soft revolution from the West, the official IRNA news agency reported.

    Javad Jahangirzadeh, a member of Majlis (parliament)'s National Security and Foreign Policy Commission, was quoted as calling on the public "to be vigilant against people to groups seeking to launch soft revolution."

    "People should be alert against people or groups that are after soft revolution since the enemies spare no efforts to harm the revolution," Jahangirzadeh said.

    He accused that "today, western states, especially the U.S., have turned to soft revolution to topple governments in democratic states by inciting public opinion."

    An official of Iran's intelligence ministry counter-espionage said on Monday that Iran had discovered and dismantled a "soft overthrow" project.

    The official, who was not named, said that his country had discovered and arrested four members of the network involved in "soft overthrow" projects against the country.

    Among the detainees, there were two brothers named Arash and Kamiar Alaei, the semi-official Fars news agency reported, adding the brothers, who were also doctors and practitioners in HIV/AIDS in Iran, had been in jail since June, 2008.

    Iran's judiciary spokesman Ali Reza Jamshidi said on Saturday that Tehran Revolutionary Court convicted and sentenced four Iranians to jail on charges of trying to topple the Islamic government with the support of the U.S. State Department and the CIA, IRNA said, without elaborating the length of the sentences.

    Iran has incessantly accused the United States and Israel of plotting against the Islamic regime by disclosing documents and trying their alleged agents in the country.

    In November 2008, Major General Mohammad Ali Jafari, Commander of the Islamic Revolutionary Guard Corps (IRGC), said that Iran had discovered an Israeli spy network.
