Iran will target economic and banking ​interests linked to the US ‌and Israel in the region after an attack on an Iranian bank, a ​spokesperson for Tehran's Khatam al-Anbiya military command headquarters said ​on Wednesday.

An administrative building linked to Bank Sepah, one of the ​country's largest public banks, which has historical links to the military, was hit overnight in Tehran, according to an Iranian ​semi-official news agency.

The spokesperson said in a statement that the US and Israel have targeted one of the Iranian banks "following their ​failed campaign."

According to the statement, this is an "illegitimate ​and uncommon action" and is freeing Iran to ​target economic centers and banks ​linked to the US and Israel in the region.

The spokesperson warned that the US should be prepared for a "painful response" and urged the people in the ​region to stay 1,000 meters away from banks.
