Armenia agreed to hand over three districts around Karabakh – Aghdam, Lachin and Kalbajar – as part of the Russia-brokered deal in early November that stopped the fighting in the Karabakh region.
Azerbaijani forces have entered the Lachin district, the last of three handed back by Armenia as part of a deal that ended weeks of fighting over Nagorno-Karabakh.
The defence ministry in Baku said in a statement on Monday that “units of the Azerbaijan army entered the Lachin region on December 1” under the deal signed in early November by Armenia, Azerbaijan and Russia.
It released a video showing a tank flying the Azerbaijani flag and leading a column of trucks into the district along a road at night.
