The UK government is organising a chartered flight to take British nationals out of Israel next week.
Britons are being asked to register interest in the flight via online forms but have been told not to travel to the airport unless told to do so.
Over the past week the government has been working with Israeli authorities on plans to arrange flights out of the country and Occupied Palestinian Territories.
The latest announcement comes after the US launched strikes at nuclear facilities in Iran overnight amid an escalation in tensions between Israel and Iran.
The Foreign, Commonwealth and Development Office has advised against all travel to Israel and the Occupied Palestinian Territories.
