Azerbaijan's border service has taken control of four villages in the Gazakh district on the border with Armenia under an agreement struck with Yerevan, Azerbaijani Deputy Prime Minister Shahin Mustafayev said on Friday.
The size of the territory returned to Azerbaijan under a border delimitation agreement on Friday was 6.5 square kilometers (2.5 square miles), Mustafayev said.
In April, Armenia said it would return the uninhabited villages to Azerbaijan, which both sides said was a milestone on the road towards a peace deal between Yerevan and Baku who have clashed for more than three decades, reported Reuters.
The decision by Armenian Prime Minister Nikol Pashinyan to hand over the four villages has triggered protests, with demonstrators calling for him to step down over what they cast as a betrayal.
Azerbaijan's retaking by force of the entirety of its Nagorno-Karabakh region in September last year, a move which sparked an exodus of ethnic Armenians living there, dealt a painful blow to Yerevan.
But it has also paved the way for an elusive deal in that it removed a long-running source of disagreement from the table.
Azerbaijan and Armenia still have other unresolved territorial disputes though, mostly focused on enclaves which the two sides want the other party to relinquish control of or provide access to.
