A senior commander in Iran’s powerful Revolutionary Guard warned that Iran will target U.S. bases in the region in the event of war with Israel, raising the prospect of a broader conflict that would force other countries to get involved, Iranian state television reported Sunday.

The comments by Gen. Amir Ali Hajizadeh, who heads the Guard’s aerospace division, came amid tension over Iran’s nuclear program and Israel’s suggestion that it might unilaterally strike Iranian nuclear facilities to scuttle what the United States and its allies believe are efforts to build a bomb. Tehran says its nuclear program is for peaceful purposes.

Hajizadeh said no Israeli attack can happen without the support of its most important ally, the United States, making all U.S. military bases a legitimate target.

“For this reason, we will enter a confrontation with both parties and will definitely be at war with American bases should a war break out,” Hajizadeh said in remarks that were posted on the website of Iran’s state Al-Alam TV. U.S. facilities in Bahrain, Qatar and Afghanistan would be targeted, he said.
