US President Donald Trump signaled Thursday that further strikes on critical infrastructure in Iran could be imminent.

"Our Military, the greatest and most powerful (by far!) anywhere in the World, hasn’t even started destroying what’s left in Iran.

"Bridges next, then Electric Power Plants! New Regime leadership knows what has to be done, and has to be done, fast!" Trump wrote on his social media platform Truth Social.

His remarks came a day after his address to the nation on Operation Epic Fury, which began on Feb. 28.

"We're going to hit them extremely hard over the next two to three weeks. We're going to bring them back to the Stone Age, where they belong," he said.
