Washington: The United States has restricted travel for its employees in Israel amid fears of an attack by Iran.
The US embassy said staff had been told not to travel outside the greater Jerusalem, Tel Aviv or Beersheba areas “out of an abundance of caution”.
Iran has vowed to retaliate, blaming Israel for a strike on its consulate in Syria 11 days ago, killing 13 people.
UK Foreign Secretary Lord Cameron has phoned his Iranian counterpart to urge against further escalation.
Israel has not claimed responsibility for the consulate attack but is widely considered to have been behind it.
