American military is likey to take more casulties in Iraq after Iran accused United States of targeting Iranians.

Iran's Foreign Minister Mataki said Iran sees U.S. "responsible" for killing Iranian people.

Motaki threatened to make America pay for its "crimes" against our people. F.M. said US will be held "accoutable".

Iran's top lawmaker, Ali Larijani, vowed that murderers "will not go unpunished". U.S. and Israel have "crossed a line" in Iraq Islamic Republic will "bring justice" to them.

It was a clearest threat to hit U.S. forces in Iraq.

Dr Larijani said killing of innocent pilgrims testify to Washington's conquest-oriented policies.

Iranian pilgrims have been killed in recent wave of bombing in Iraq. Iran has laid the blame on U.S. "occupying" forces, and threatened to hit those resonsible Iranian deaths.

Iran is likely to punish U.S. troops in Iraq after a series of mysterious bombings killed scores of Iranian pilgrims. Two latest bombs exploded on 23 and 24 April killing mainly Iranians.

Foreign Ministry Spokesman, Kashkawi accused U.S. forces are behind the wave of bombings.

One of the most powerful men in Iran, Ali Rafsanjani, also pointed the finger at U.S. blaming its military for the violence. He said U.S. "does not care" for Iranian deaths.

Supreme Leader of Iran, Ayatollah Ali Khamenei, said U.S. forces were "the main suspects" in bomb attacks.

Khamenei, who has the final say on all matters, slamed the U.S. forces, saying they have "on the pretext of confronting terrorism, had occupied a muslim country and killed tens of thousands of people in Iraq".

Iran's Supreme Leader also hit out at Israel, another arch-foe: "Terrorism in Iraq is a poison that will be on the record of America."

Ayatollah Khamenei went further and accused U.S. and Israeli secret services. "CIA and Israeli agents are the prime suspects of terrorism."

Khamenei told Iranians that U.S. was responsible for deaths of Iranians visiting Iraq in April 2009. "The main suspects in this crime and atricoties similar to that, are American security and military forces", he said. U.S. forces “have massacred tens of thousands of people and made Iraq more insecure on a daily basis.”

U.S. President Obama has vowed to pull troops from Iraq by August 2010. George Bush had made plans to stay in Iraq "for decades".

Iranian threats make it unlikely that U.S. would be able to peacefully withhdraw its forces from Iraq.

Iran is said to getting ready to inflict a painful lesson on U.S. military. It said "preparations are underway" to make the exit a humiliaitng experience for America. Officials said that "necessary measures are underway" to avenge massacre of Iranians.
