ISIS has taken aim at Donald Trump - saying that the US is "being run by an idiot". In their first official remarks since Trump took office, the terror group mocked the President claiming he is ignorant.
Spokesman Abi al-Hassan al-Muhajer said: "America you have drowned and there is no saviour, and you have become prey for the soldiers of the caliphate in every part of the earth, you are bankrupt and the signs of your demise are evident to every eye."
"There is no more evidence than the fact that you are being run by an idiot who does not know what Syria or Iraq or Islam is," he said in a recording released on Tuesday on messaging network Telegram.
Trump has made defeating Islamic State a priority of his presidency.
US-backed forces are fighting to retake Islamic State's two biggest cities - Mosul in Iraq and Raqqa in Syria.
"Die of spite America, die of spite, a nation where both young and old are racing to die in the name of God will not be defeated," al-Muhajer said.
Trump is examining ways to accelerate the US-led coalition campaign that U.S. and Iraqi officials say has so far been largely successful in uprooting Islamic State militants in Iraq and Syria.
The loss of Mosul, Islamic State's last major stronghold in Iraq, would deal a major defeat to Islamic State.
