WASHINGTON

US President Donald Trump said Wednesday that the US is closely watching the straits in the Middle East after asserting that American forces destroyed Iranian naval vessels during an ongoing military operation.

"Now we're going to look very strongly at the straits. The straits are in great shape. We've knocked out all of their boats. They have some missiles, but not very many," he told reporters.

Trump said he believes the US is in "very good shape" in its war with Iran.

"The main thing is we have to win this," he added.
