GLOBAL TERRORISM WARNING
You should be aware of the global risk of indiscriminate attacks that could take place at anytime, anywhere, including in places frequented by expatriates and foreign travellers.
When overseas, you should always maintain at least the same level of vigilance as you would in the UK and take sensible precautions. If you see or hear anything suspicious, you should inform the appropriate authorities or security forces.
The FCO uses four broad threat descriptors to inform you of the terrorist threat overseas. See Risk of Terrorism.
