"This is my house, I can't leave it to the Turks," as Azerbaijanis are often called by Armenians, said one resident as he threw burning wooden planks and rags soaked in gasoline into a completely empty house.
Azerbaijan and Armenia agreed on a deal with Russia to end weeks of fierce clashes over Nagorno-Karabakh on Tuesday, after Russian peacekeeping troops deployed to the war-ravaged enclave of the region.
Troops moved into the district of Aghdam, one of three due to be handed back, the Azerbaijan defence ministry said, a day after columns of Armenian soldiers and tanks rolled out of the territory.
Azerbaijan's President Ilham Aliyev has repeatedly said there would be no halt to fighting until Armenian troops withdraw and vowed to continue the intervention until his army captured all of Karabakh.
Azerbaijan and Armenia accused each other on Saturday of attacks in violation of a Russian-brokered truce, as the worst fighting in the South Caucasus since the 1990s continued.
The six-week conflict between Azerbaijan and ethnic Armenian forces over the region and its surrounding areas was brought to a halt by a Russian-brokered ceasefire deal last month.
Fighting has continued overnight between Azerbaijan and its ethnic Armenian mountain enclave of Nagorno-Karabakh, the Azeri defence ministry said on Tuesday, in the fiercest round of the decades-old conflict in more than a quarter of a century.
The defence ministry of the Nagorno-Karabakh said on Monday it had recorded another 44 casualties among its military, pushing its military death toll to 1,221 since fighting with Azeri forces erupted on Sept.27.
Azerbaijan and ethnic Armenian forces clashed in several areas of Nagorno-Karabakh on Friday, hours before talks were due to start in Washington to try to end the deadliest fighting in the mountain enclave for over a quarter of a century.
