Iran's top general is threatening to strike American troops in the Middle East if threatened militarily.
Maj. Gen. Hassan Firouzabadi also warned a military strike would threaten oil supplies. This comes as President Barack Obama urged United Nation members to back sanctions to curb Iran's nuclear program.
"If America presents Iran with a serious threat and undertakes any measure against Iran, none of the American soldiers who are currently in the region would go back to America alive," Firouzabadi was quoted as saying by the semi-official Fars news agency.
"If America wants to have the region's oil and its markets then the region's markets would be taken away from America and the Muslims' control over oil would increase," Firouzabadi said, according to state broadcaster the Islamic Republic of Iran Broadcasting (IRIB).
Russian President Dmitry Medvedev said he was displeased with Iran's stance over Iran's nuclear program, which the West believes is aimed at making atomic weapons.
"Tehran is not reacting to a range of suggested constructive compromise agreements. We can't close our eyes to this. That is why I do not exclude that Security Council will have to examine this question again," Medvedev told reporters.
U.S. troops are currently engaged in Iraq and Afghanistan, both of which border Iran.
Iran has extended the same warning to Israel.
