Israel and Iran have traded more missile attacks despite international calls for a halt to the fighting, with neither country showing signs of backing down as the conflict between the regional foes raged for a third day.

Trump warns Iran not to retaliate against U.S. targets in the Middle East while also predicting Israel and Iran would 'soon' make a deal to end their escalating conflict.

"The full strength and might of the U.S. Armed Forces will come down on you at levels never seen before," Trump warned.
