President Trump is leaning toward expanding U.S. military operations in Iran after days of briefings from top aides, U.S. officials said. 

Options include stepping up airstrikes, sending ground forces to seize Iranian islands near the Strait of Hormuz and bombing a fortified site that could be used for covert nuclear work.

Trump hosted a Situation Room meeting Tuesday evening to discuss the potential seizure of Kharg Island and other territory along the Strait of Hormuz using U.S. troops, as well as the potential bombing of a tunnel complex at Pickaxe Mountain, a nuclear-linked site the U.S. has yet to target. Expanding airstrikes against more targets in Iran, including energy sites, also remains a possibility.
