Iran has threatened reprisals against Israel over the strike in the Syrian capital on April 1, which killed seven Islamic Revolutionary Guard Corps members, including two generals, leading to fears of an escalation of violence in the Middle East.
The French Ministry for Europe and Foreign Affairs on Friday advised its citizens against travelling to Iran, Lebanon, Israel and the Palestinian territories.

The UK told its citizens to avoid all but essential travel to Israel and the occupied Palestinian territory over the “possibility of an attack on Israeli territory from Iran”.
