The United Kingdom has advised its citizens to avoid travelling to Israel and the occupied Palestinian territory over the “possibility of an attack on Israeli territory from Iran,” the British foreign office said.

In its latest update, the foreign office advises against “all travel” to northern Israel, Gaza, areas near Gaza and the occupied West Bank — excluding East Jerusalem and Route 1 between Jerusalem and Tel Aviv.

It also advised against “all but essential travel” to the rest of Israel and the occupied Palestinian territory.
