Azerbaijan's army has entered the Lachin region following 28 years of occupation by Armenian forces, the country's Defense Ministry announced early Tuesday local time.
"According to the trilateral statement signed by the presidents of the Republic of Azerbaijan, the Russian Federation and the prime minister of the Republic of Armenia, units of the Azerbaijan Army entered the Lachin region on Dec. 01," the ministry said.
Relations between the former Soviet republics of Azerbaijan and Armenia have been tense since 1991, when the Armenian military occupied Nagorno-Karabakh, also known as Upper Karabakh, a territory recognized as part of Azerbaijan, and seven adjacent regions.
When new clashes erupted on Sept. 27, the Armenian army launched attacks on civilians and Azerbaijani forces and violated humanitarian several cease-fire agreements.
During the 44-day conflict, Azerbaijan liberated several cities and nearly 300 settlements and villages from the Armenian occupation.
On Nov. 10, the two countries signed a Russia-brokered agreement to end fighting and work toward a comprehensive resolution.
The truce is seen as a victory for Azerbaijan and a defeat for Armenia, whose armed forces have been withdrawing as the agreement specified.
