Dubai – Iran condemned Donald Trump on Sunday as a “terrorist in a suit” after the US president threatened to hit 52 Iranian sites hard if Tehran attacks Americans or US assets in retaliation for the killing of military commander Qassem Soleimani.

As the two countries assailed each other in a war of words, the European Union, Britain and Oman urged the parties to seek to de-escalate the crisis.

Soleimani, Iran’s pre-eminent military commander, was killed on Friday in a US drone strike on his convoy at Baghdad airport, an attack that took long-running hostilities between Washington and Tehran into uncharted territory and raised the spectre of wider conflict in the Middle East.

“Like ISIS, Like Hitler, Like Genghis! They all hate cultures. Trump is a terrorist in a suit. He will learn history very soon that NOBODY can defeat ‘the Great Iranian Nation & Culture’,” Information and Telecommunications Minister Mohammad Javad Azari-Jahromi tweeted.

Soleimani was the architect of Tehran’s overseas clandestine and military operations as head of the Revolutionary Guards’ Quds Force. Supreme Leader Ayatollah Ali Khamenei promised on Friday that Iran would seek harsh revenge for his death.
