The FCO (Foreign & Commonwealth Office) is the British government department that issues advice as to whether a country is considered unsafe to travel to. Airlines and Tour Operators here in the UK will generally follow advice given by the FCO regarding travelling to and from a country and we will endeavour to warn you of anything that is reported. The FCO website https://www.gov.uk/government/organisations/foreign-commonwealth-office also features information on a selection of subjects which are useful when travelling overseas.
