Baku, Azerbaijan, has been temporarily suspended from the Schengen area of passport-free travel, due to a travel advisory issued by EU member states.
The travel advisory came after a Russian air crash on Wednesday that killed at least 22 people.
The Russian airline, Red Wings, had announced that it would suspend its flights from Baku until further notice.
Russia’s government has previously threatened to stop all flights to and from the country if a new travel advisory is issued by the European Union.EU officials in Brussels have also expressed their concern over the new travel advisories, with some even warning the country that it could face sanctions by the bloc if it does not comply with the decision.
A source close to Azerbaijan’s foreign ministry told AFP that the travel advisory was not a travel warning, but an indication that the country was in a difficult situation.
The country has been in a “critical situation” over the last few weeks, the source added.
The Baku region is located in the Caucasus mountains in what is known as the Black Sea region.
Baku is currently one of the most secure areas of the Schendler Zone in Europe, with a number of security checks at the entrances to the Scheldtland border.
Russia, which has been a long-time ally of Azerbaijan, was the first member of the European Parliament to call for the travel advisors suspension.
Bashar Assad, leader of the Syrian opposition and a member of Azerbaijan’s ruling ruling coalition, has also called for the suspension of all EU travel to Azerbaijan, and said he was prepared to offer the country financial compensation if that were needed.
In a tweet on Thursday, the Russian foreign ministry called the advisory “an act of aggression” and said that it “is part of a concerted plan to undermine Azerbaijan’s national security”.
Baku has been the subject of diplomatic tensions between the two countries, with Moscow’s envoy to the country accusing the country of violating EU rules.
Russia has previously imposed sanctions on the Azerbaijan government over its human rights record.
In January, the country’s parliament voted to remove President Ilham Aliyev from office, following protests in the country over his government’s decision to grant amnesty to thousands of detained and tortured opposition activists.
The European Union has said it is working to implement a visa ban on Azerbaijan that would apply to its citizens from 11 countries and bars its citizens and businesses from doing business with the country.
The EU has also said it will consider an emergency measure against Azerbaijan if it fails to implement the measures by mid-October.
