The Foreign and Commonwealth Office (FCO) advise against all travel to Nagorno-Karabakh and the military occupied area surrounding it. There have been ceasefire violations along the Armenia-Azerbaijan border and Line of Contact which resulted in a number of deaths and casualties. Anyone who has visited Nagorno-Karabakh without the permission of the Azerbaijani authorities will be refused entry to Azerbaijan. All British nationals travelling to Azerbaijan must obtain a visa in advance. There is a general threat from terrorism. Around 7,000 British nationals visit Azerbaijan every year, mainly on business. Most visits are trouble free.
