After more than a century of conflict and the mass exodus of its Armenian population in September 2023, the self-styled republic of Nagorno-Karabakh has officially ceased to exist and is now fully under the rule of Azerbaijan.

A UN mission said it was struck by the "sudden manner" more than 100,000 people left the separatist region over the past week. Meanwhile, Armenia called for on the European Union to sanction Azerbaijan.

Most of the Armenian population of Nagorno-Karabakh have fled to Armenia since Azerbaijan launched its offensive to retake control the enclave.

Josep Borrell, the EU's high representative for foreign and security policy, speaks to Talking Europe from New York, where he is attending the annual United Nations General Assembly.

Baku's Defense Ministry earlier blamed six deaths in the breakaway Nagorno-Karabakh region on Armenian separatists. It comes three years after a war with neighboring Armenia over the region.

Azerbaijan's breakaway Nagorno-Karabakh region has been cut off from much-needed supplies since December, when Azerbaijan closed the one road connecting the region to ally Armenia, saying it was an arms smuggling route.

In just a day, Azerbaijan was able to force ethnic Armenians in Nagorno-Karabakh to disarm. Usually, Armenians would look to Russia for help, but Russian peacekeepers stayed well out of the recent conflict. Why?
