US President Donald Trump said Monday that the United States will retaliate against Iran following missile and drone attacks on American forces in Jordan and the United Arab Emirates (UAE).

“We’re going to hit them hard. There will be a response,” Trump told Fox News.

He noted that US air defense systems intercepted most of the incoming fire. One missile was identified as “not going to hit anything significant,” and US forces allowed it to pass through the airspace, Trump said.
