The Federal Aviation Administration is prohibiting all U.S. airlines from flying into Israel's Ben Gurion International Airport for 24 hours.
The order comes after a rocket landed one mile from the Tel Aviv airport Tuesday morning. Several airlines had already suspended service between the U.S. and Tel Aviv in response to the rocket strike.
A Delta Boeing 747 from New York was headed for Tel Aviv Tuesday when it turned around and flew to Paris instead. Flight 468 had 273 passengers and 17 crew on board.
The Port Authority of New York and New Jersey says Delta operates one flight a day between JFK International Airport and Tel Aviv.
There has been growing concern around airline safety after a Malaysia Airlines jet was shot down over Ukraine last week, killing everyone aboard.
