CNBC reports that U.S. airlines have "canceled hundreds of flights to airports in Puerto Rico and Aruba, according to flight tallies from FlightAware and carriers' sites." JetBlue, Southwest, and American Airlines were among the multiple airlines showing cancelled flights, which "included close to 300 flights to and from San Juan, Puerto Rico's Luis Muñoz Marín International Airport, more than 40% of the day's schedule, according to FlightAware." Airlines canceled flights throughout the Caribbean on Saturday following U.S. strikes on Venezuela after the Federal Aviation Administration ordered commercial aircraft to avoid airspace in parts of the region.... It wasn't immediately clear how long the disruptions would last, though such broad restrictions are often temporary. Airlines said they would waive change fees and fare differences for customers affected by the airspace closures who could fly later in the month. CNN cites a U.S. official who says more than 150 U.S. aircraft (including helicopters) launched from 20 different bases "on land and sea" during Friday's attack. The U.S. has said the lights were out in Caracas during the attack, presumably because of a targeted strike on their power grid. "Videos filmed by Caracas residents showed parts of the city in the dark," reports the Miami Herald. United Nations secretary-general António Guterres issued a statement via his spokesman saying he was "deeply concerned that the rules of international law have not been respected," (according to a Reuters report cited by the Guardian). The Guardian adds that "a number of nations have called for an emergency meeting of the UN Security Council, in New York, today, as a result of the U.S.'s unilateral action."
