Iranian Foreign Minister Mohammad Javad Zarif on Thursday accused U.S. President Donald Trump of attempting to fabricate a pretext to attack Iran, and said Tehran would defend itself forcefully. Separately, a military adviser to Iran’s supreme leader warned Trump “not to turn the New Year into mourning for Americans”. Zarif said in a tweet: “Instead of fighting Covid in US, @realDonaldTrump & cohorts waste billions to fly B52s & send armadas to OUR region. Intelligence from Iraq indicate plot to FABRICATE pretext for war.” The U.S. military flew two nuclear-capable B-52 bombers to the Middle East in a message of deterrence to Iran on Wednesday, but the bombers have since left the region.
