Dubai | US President Donald Trump issued a new threat online to Iran, writing: "Watch what happens to these deranged scumbags today."

Trump made the post Friday on his Truth Social website, saying that "Iran's Navy is gone, their Air Force is no longer, missiles, drones and everything else are being decimated, and their leaders have been wiped from the face of the earth."

"They've been killing innocent people all over the world for 47 years, and now I, as the 47th President of the United States of America, am killing them," Trump wrote. "What a great honour it is to do so!"
