TEHRAN, Iran (AP) — An Iranian commander is warning the United States over a possible military move against the Tehran-backed regime of Syrian President Bashar Assad.

The semi-official Fars news agency, which has close ties to Iran’s powerful Revolutionary Guard, quotes Gen. Masoud Jazayeri as warning that “trespassing over the red line in Syria will have severe consequences for the White House.”

Gen. Jazayeri did not provide details but said Washington is well aware of such red lines. He said the war in Syria is a product of a U.S. plot and “regional reactionary” countries, a common reference to Saudi Arabia and Qatar.

Earlier Saturday, Washington said U.S. naval forces are moving closer to Syria as President Barack Obama considers a military response to Assad’s alleged use of chemical weapons.
