Delta Air Lines is canceling all flights to Israel until further notice, citing reports that a rocket landed near Tel Aviv’s Ben Gurion Airport.

A Delta Boeing 747 from New York was flying over the Mediterranean headed for Tel Aviv today when it turned around and flew to Paris instead. Flight 468 had 273 passengers and 17 crew on board.

US Airways, which has one daily flight from Philadelphia, canceled that flight today and the return trip from Tel Aviv.

United Airlines, which has two flights daily to Israel out of Newark, N.J., did comment immediately on the status of those flights.

Airlines and passengers are growing more anxious about safety since last week, when a Malaysia Airlines jet was shot down over Ukraine, killing all 298 people on board.
