"The UK advises against all travel to Syria and parts of Iraq. Anyone who does travel to these areas, for whatever reason, is putting themselves in considerable danger.

"Everyone who returns from taking part in the conflict in Syria or Iraq must expect to be investigated by the police to determine if they have committed criminal offences, and to ensure that they do not pose a threat to our national security.

"There are a range of terrorism offences where individuals can be convicted for crimes committed overseas and we can also use Temporary Exclusion Orders to control an individuals' return to the UK."
