Iran live updates: After launching strikes, US warns of escalation if Iran responds

The strikes follow attacks against commercial shipping and service members.

President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.

Delegations from the U.S. and Iran entered negotiations in June aimed at a war-ending deal based on a memorandum of understanding signed by both countries.

The U.S. and Iran have nonetheless continued to exchange strikes, with the strategic Strait of Hormuz as the primary flashpoint.

The Kuwait Army issued an alert that its air defenses are "confronting hostile missile and drone attacks."

"The General Staff of the Army notes that if explosion sounds are heard, they are the result of air defense systems intercepting the hostile attacks," the Kuwait Army said.

Over a dozen ballistic missiles were fired at Jordan were but all were intercepted or fell in remote areas Tuesday, Jordanian officials said.

Separately, a U.S. official told ABC News that U.S. forces shot down Iranian missiles, but didn't give more specifics.

Jordanian Armed Forces said that it intercepted 10 missiles and three fell "in remote areas far from population centers."

Iranian state media said Iran is now striking back after the U.S. launched strikes against Islamic Revolutionary Guard Corps targets on Tuesday.

Iranian state media Tasnim news claimed an American MQ9 drone was shot down by a new Iranian air defense system in the Khomein area.

President Donald Trump confirmed that the U.S. is currently striking Iranian targets near the Strait of Hormuz, posting on social media that these strikes are "retaliation" to Iran’s "failed attempt at adding sea mines" to the strait and because of its strikes on a U.S. military base in Jordan over the weekend.

"The strikes are large and powerful, and in retaliation for the Iranians’ failed attempt at adding sea mines to the Strait, which currently has no mines (They have been completely removed or detonated!), and the Iranians shooting eight missiles, all successfully knocked down, at our Military Base in Jordan,” Trump said on his social media platform on Tuesday.

On Sunday, a U.S. official said the U.S. struck Iranian rocket launch sites, claiming the IRGC had been preparing rockets armed with sea mines-- an attack that prompted Iran to respond with strikes in Jordan and the UAE.
