The news came after the U.S. announced it had killed Iranian Gen. Qassem Soleimani, commander of the Islamic Revolutionary Guard Corps' elite Quds Force.
Top Democrats condemned President Trump's decision to take out Iran's Qasem Soleimani, in contrast to Republicans' reaction to Osama bin Laden's demise.
'The loss of our dear General is bitter,' Khamenei tweeted. 'The continuing fight & ultimate victory will be more bitter for the murderers & criminals.'
Iranian Defense Minister Amir Hatami vowed to take 'crushing revenge' for the US airstrike that killed Qasem Soleimani, the leader of Iran’s elite Quds Force.
