It said 18 drones and seven cruise missiles were fired from a direction that ruled out Yemen as a source.

Iran has denied any involvement and warned it would retaliate against any attack that targeted it.
The US has stood by its accusation that Iran was behind the attacks.
Secretary of State Mike Pompeo said it was an "act of war".
