23 May 2004 -- Iran, a country run by Shi'ite Muslims, has issued a "formal warning" to the United States over its policy in Iraq as U.S. tanks and troops increased their presence in the Shi'ite holy cities of Kufa, Al-Najaf, and Karbala overnight.
French news agency AFP said Iran's Foreign Ministry spokesman, Hamid Reza Assefi, told reporters at a news conference today that the warning was issued because of the seriousness of developments in Iraq.
CNN reported that U.S. troops killed 16 suspected insurgents and seized a cache of weapons in a mosque in Kufa, which is near the holy city of Al-Najaf, where fighting and some casualties were also reported.
Witnesses said U.S. forces also briefly raided Karbala, some 80 kilometers north of Al-Najaf.
