Officials in Dubai said flights have been suspended after a nearby drone strike caused a fire. No injuries have been reported.

Dubai Civil Defense teams successfully contained the fire, officials said.

Flights were suspended "as a precautionary measure to ensure the safety of all passengers and employees," Dubai's Aviation Authority announced.

As the war in Iran enters its third week, President Donald Trump told reporters on Air Force One Sunday night that he is talking to countries about policing the Strait of Hormuz, saying he is looking at “about seven,” but declined to give specifics on which countries they may be.

Trump also said that the Strait of Hormuz is “something that we don't need,” arguing that other countries should step in and assist because it affects them more than the U.S.

“I really am demanding that these countries come in and protect their own territory, because it is their territory. It's the place from which they get their energy, and they should come and they should help us protect it,” the president said.

Trump also suggested the U.S. not assist at all.

“You could make the case that maybe we shouldn't be there at all because we don't need it. We have a lot of oil people with the number one producer anywhere in the world,” he said.

As President Donald Trump continues to urge countries to assist with the escalating crisis in the Strait of Hormuz, he reportedly issued a warning to NATO on Sunday, saying it will be “very bad” for the global alliance if they do not respond or comply.

“If there’s no response or if it’s a negative response, I think it will be very bad for the future of NATO,” he reportedly told the Financial Times in a phone interview.

The president has spent the weekend insisting that because other countries, particularly Europe and China, are dependent on the oil that flows through the Strait, they should be responsible for assisting with the escalating oil crisis.

“It’s only appropriate that people who are the beneficiaries of the Strait will help to make sure that nothing bad happens there,” Trump said.

The president also floated postponing his trip to Beijing to meet with Chinese President Xi Jinping, which a White House official previously told ABC is currently scheduled for March 31 to April 2. He did not say how long he may delay the trip.

Trump told the FT that he would “like to know” if China would help with unblocking the Strait of Hormuz before the summit takes place.

The spokesperson also said that Starmer had spoken Sunday with Canadian Prime Minister Mark Carney and "discussed the situation in the Middle East, including the impact of the continued closure of the Strait of Hormuz on international shipping."

“They agreed to discuss the ongoing conflict further in their meeting tomorrow, among other bilateral issues,” the spokesperson said.

President Trump on Saturday called for other countries, including the U.K., to step in and assist with the escalating crisis in the Strait of Hormuz.
