The leaders of Armenia and Azerbaijan have agreed to meet in Brussels on August 31 for talks mediated by the European Union, the Armenian government said on August 25.
European Council chief Charles Michel will be present at the meeting.
The meeting comes after an outbreak of fighting over the breakaway region of Nagorno-Karabakh on August 1-3 in which at least one Azerbaijani and two ethnic Armenian soldiers were killed. The two sides blame each other for the violence.
The last meeting between the two leaders was held in Brussels on May 22, at Michel's initiative.
Azerbaijan and Armenia have been locked in a conflict over Nagorno-Karabakh for years.
The mostly Armenian-populated region that had the status of an autonomous oblast within Soviet Azerbaijan declared its independence from Baku amid the Soviet Union's disintegration, triggering a 1992-94 war that claimed an estimated 30,000 lives and displaced hundreds of thousands of people.
The war ended in a Russia-brokered cease-fire, leaving Nagorno-Karabakh's ethnic Armenians in control of most of the region as well as several adjacent districts of Azerbaijan proper.
Internationally mediated negotiations with the involvement of the OSCE Minsk Group -- co-chaired by the United States, Russia, and France -- failed to result in a resolution before another large-scale war broke out in September 2020.
The 44-day conflict that killed more than 6,500 people ended in a Moscow-brokered cease-fire, with Azerbaijan regaining control of all districts surrounding Nagorno-Karabakh as well as large swaths of territory inside the former autonomous region itself. Some 2,000 Russian peacekeepers were deployed in the region to oversee the truce.
Armenia and Azerbaijan fought two wars -- in 2020 and in the 1990s -- over Azerbaijan's Armenian-populated region of Nagorno-Karabakh.
Six weeks of fighting in the autumn of 2020 claimed more than 6,500 lives and ended with a Russian-brokered cease-fire agreement.
Armenia was forced to cede swathes of territory it had controlled for decades, and Russia deployed some 2,000 peacekeepers to oversee the fragile truce, but tensions persist despite the cease-fire agreement.
In early August, new tensions flared as Azerbaijan said it had lost a soldier and the Karabakh army said two of its troops had been killed and more than a dozen injured.
