Germany's Foreign Office confirmed on Tuesday that it welcomes Azerbaijan’s decision to allow international observers from the United Nations to watch over the situation in Nagorno-Karabakh.

Over social media, the Office posted: "It is a positive step that Azerbaijan has allowed UN observers into Nagorno-Karabakh for the first time. They need a permanent presence, as only transparency can build trust in Azerbaijan's promise to protect the rights of all residents & returnees to the region." 

This marks the first UN mission in around 30 years in the Armenian-populated and governed Nagorno-Karabakh in Azerbaijan.

According to data by Armenia, around 100,500 people have already moved to Armenia since Azerbaijan launched the operation that it named "local anti-terrorist activities" in Nagorno-Karabakh on September 19 to "restore the constitutional order."

Armenia, in turn, called the operation an aggression against the population of Nagorno-Karabakh.

Under the mediation of Russian peacekeepers, Nagorno-Karabakh's authorities agreed to disarm and surrender all their weaponry to Baku the following day. Notably, Armenia was not a party to these negotiations.

The Azerbaijani government committed to facilitating the "integration" of Nagorno-Karabakh Armenians who choose to remain in the region.

On September 28, Azerbaijan said it wanted ethnic Armenians to remain in Nagorno-Karabakh after it took full control of the region.
