The head of Iran’s joint military command has vowed to kill one member of the US forces for every Iranian killed.

Major General Abdollahi, commander of Iran’s Khatam Al-Anbiya Central Headquarters, stated that “for every Iranian martyred, one American soldier will be sent to hell,” The Caspian Post reports, citing Al Jazeera.

Abdollahi also issued a warning to the U.S., saying, “We have prepared free and direct tickets to hell for you.”
