After ordering the assassination of a top Iranian commander without giving notice to congressional leaders, United States President Trump has told Congress to follow him on Twitter for updates on his acts of war against Iran.

“These Media Posts will serve as notification to the United States Congress that should Iran strike any US person or target, the United States will quickly & fully strike back, & perhaps in a disproportionate manner,” Mr Trump wrote.

He continued: “Such legal notice is not required, but is given nevertheless!”

American forces on Friday killed Iranian military commander Qassem Soleimani, fuelling anti-American protests across Iran and ratcheting up tensions between the two longtime adversaries.
