Azerbaijani military has liberated the city center of Qubadli and some villages from Armenian occupation, President Ilham Aliyev said Sunday.

Aliyev said on Twitter that the Azerbaijani army liberated the city center, as well as some villages in Qubadli, Zengilan and Jabrayil.

"Long live Azerbaijan's Army! Karabakh is Azerbaijan!" he added, referring to efforts to liberate Nagorno-Karabakh, from nearly 30 years of Armenian occupation.

Russia's Ria Novosti news agency reported later in the day that the Armenian Defense Ministry confirmed Qubadli's capture by Azerbaijani troops.

Since new clashes erupted between the two countries on Sept. 27, Armenia has continued its attacks on civilians and Azerbaijani forces.

Relations between the two former Soviet republics have been tense since 1991 when the Armenian military occupied Nagorno-Karabakh, an internationally recognized territory of Azerbaijan.

Multiple U.N. resolutions, as well as international organizations, demand the withdrawal of the occupying forces.

About 20% of Azerbaijan's territory has remained under illegal Armenian occupation for nearly three decades.

World powers, including Russia, France, and the U.S., have urged a new cease-fire. Turkey, meanwhile, has supported Baku's right to self-defense and demanded the withdrawal of Armenia's occupying forces.
