The government announced late on Thursday that it was upgrading the travel advisory for Tunisia in the wake of the beachside gun attack last month that killed 38 tourists, 30 of whom were British.

In a statement the Foreign Office said it now advises "against all but essential travel to Tunisia" amid intelligence reports warning of further terror attacks and concerns that the local authorities are unable to adequately respond to such threats.

In March, two gunmen killed 22 tourists at the famous Bardo museum in the capital of Tunis.

All travel in certain areas on the Libyan and Algerian borders is now advised against, and the Foreign Office has recommended that all Brits in the country make arrangements to come home as soon as possible.

Unlike the US State Department, which takes into account whether there is an embassy or consulate to assist citizens in their destination of choice, the Foreign Office's definitions are focussed on physical safety - so North Korea carries few warnings because of a low level terror and violence threat, but options if you do run into trouble there are limited.

While countries that are internally being torn apart like Somalia, the Central African Republic, Yemen and Syria are all strictly no-go zones, other countries that currently carry "all but essential" warnings, with some areas marked as "all travel advised against" are:

- Afghanistan

- Burundi

- Chad

- Iran

- Iraq

- Mauritania

- Mali

- Niger

All of these countries have ongoing conflicts between government and rebel forces such as al-Qaeda, Isis, and al-Qaeda in the Islamic Maghreb (Aqam).

In Burundi, there is widespread fighting between the government, which has delayed parliamentary elections, and opposition forces.

As a whole, the Foreign Office currently rates Tunisia as a more dangerous place than Nigeria, Pakistan and Israel and Palestine.
