US air deployments rise in Middle East as Trump warns Iran of 'massive' attack: 'Bigger than ever'

US military aircraft and equipment movements toward the Middle East have increased, suggesting preparations for a possible operation.

President Donald Trump told Axios he is considering a 'massive' attack on Iran, 'bigger than ever before', and is 'close' to making a decision.

Two US officials confirmed no new orders have been issued to the military and no decision has been made.

Trump said Israel could participate in US military action against Iran if requested, but Washington does not need allies to launch an operation.

Tensions have risen as oil prices cross $100 per barrel amid US operations against Iranian attacks on commercial vessels in the Strait of Hormuz.
