Hundreds of flights were canceled across the Caribbean on Saturday, including more than 20 departing from or bound for Chicago, after the United States carried out large-scale strikes in Venezuela and captured President Nicolás Maduro.

Secretary of Transportation Sean Duffy said in a post on X the Federal Aviation Administration restricted airspace in the Caribbean and Venezuela “to ensure the safety of the flying public.”

The restrictions will be lifted when appropriate, he said, however a timeline hasn’t been provided.

At O’Hare International Airport, the majority of flight cancellations were connected to Luis Munoz Marin International Airport in San Juan, Puerto Rico. As of 3 p.m., a total of 10 flights either heading to or from San Juan had been canceled.
