Iran live updates: UAE says it intercepted Iranian missiles and drones

The United Arab Emirates' foreign affairs ministry said it "reserves its full and legitimate right to respond to" Iranian missile and drone attacks, which it said targeted civilian sites and facilities.

The ministry called Monday's attacks, which mark the first time any Gulf country has come under significant attack by Iran since the ceasefire took hold in early April, a "dangerous escalation and an unacceptable transgression."

The White House did not immediately respond to ABC News when asked about the attacks on the UAE and what they mean for the ceasefire.

When asked about the attacks during an update on "Project Freedom," Adm. Brad Cooper, the head of U.S. Central Command, told reporters that he would "refer to the UAE on that."

"That's really a matter under their national jurisdiction and not part of our project operation," he said.

President Donald Trump said that Iran is "taking shots" at ships from countries not involved with the U.S.-Iran conflict in the Strait of Hormuz, in violation of "Project Freedom."

"Iran has taken some shots at unrelated Nations with respect to the Ship Movement, PROJECT FREEDOM, including a South Korean Cargo Ship," Trump posted on his social media platform.

"Other than the South Korean Ship, there has been, at this moment, no damage going through the Strait," he added.

The U.S. took out six small Iranian boats that were "threatening commercial shipping" on Monday, Adm. Brad Cooper, the head of U.S. Central Command, told reporters during an update on "Project Freedom."

Cooper said that over the past 12 hours, the Islamic Revolutionary Guard Corps has been launching missiles, drones and small boats toward ships the U.S. was protecting in the Strait of Hormuz, and that the U.S. "defeated each and every one of those threats" through defensive munitions. AH-64 Apache attack helicopters and others were used to "eliminate" the boats, he said.

No U.S. military ships have been struck, Cooper said.

The United Arab Emirates' Ministry of Defense said it is "currently engaging" with air attacks from Iran, and that its air defense systems were intercepting ballistic missiles, cruise missiles, and drones.

This marks the first time the UAE, or any Gulf country, has come under significant attack by Iran since the ceasefire took hold in early April.

Multiple flights headed to the UAE are now diverting to Muscat, Oman, amid reports of drone and missile attacks, according to Flightradar24 data.

Amid the reports, the British military’s United Kingdom Maritime Trade Operations center also said a cargo ship was on fire off the coast of the UAE. The cause of the fire was not yet confirmed.
