Demonstrators hold their fists in the air during a rally to demand the reopening of a blockaded road linking the Nagorno-Karabakh region to Armenia and to decry crisis conditions in the region in Stepanakert on July 14, 2023.
Azerbaijani President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan met in Brussels for talks aimed at resolving their decades-long conflict for the control of Armenian-populated Karabakh, the foreign ministry in Baku said in a statement.
European Council President Charles Michel was mediating the discussions, which come amid renewed tensions after Azerbaijan closed temporarily the Lachin corridor, the sole land link between Karabakh and Armenia.
Adding to the standoff, Azerbaijan's defence ministry said Armenian separatist forces in Karabakh "use radio interference against GPS navigation systems of local and foreign airlines' passenger aircraft flying through our country's airspace."
The alleged interference impacted two Azerbaijan Airlines aircraft on Thursday, the ministry said.
"Such incidents pose a serious threat to aviation safety," according to the statement.
Karabakh's rebel authorities denied the claims, calling them an "absolute lie."
Uneasy peace talks
On Friday, some 6,000 people rallied in Karabakh to demand the reopening of the Lachin corridor.
Local separatists, warning of a humanitarian crisis, urged Moscow to ensure free movement through the road.
Azerbaijan later allowed the Red Cross to resume medical evacuations from Karabakh to Armenia.
Karabakh has been at the centre of a decades-long territorial dispute between the two countries, which have fought two wars over the mountainous territory, mainly populated by Armenians.
In autumn 2020, Russia sponsored a ceasefire agreement that ended six weeks of fighting between Armenian and Azerbaijani forces for control of Karabakh.
The deal saw Armenia cede swathes of territories it had controlled for decades, while Russia deployed peacekeepers which are manning the five-kilometre-wide Lachin Corridor to ensure free passage between Armenia and Karabakh.
Baku and Yerevan have been seeking to negotiate a peace agreement with the help of the European Union and United States, whose diplomatic engagement in the Caucasus has irked traditional regional power broker Russia.
During previous rounds of Western-mediated talks, Baku and Yerevan have made some progress towards preparing the text of a peace agreement, but its signature remains a distant prospect.
Yerevan agreed to recognise Karabakh as part of Azerbaijan, but demanded international mechanisms for protecting the rights and security of the region's ethnic-Armenian population.
Baku insists such guarantees must be provided at the national level, rejecting any international format.
When the Soviet Union collapsed in 1991, ethnic Armenian separatists in Karabakh broke away from Azerbaijan. The ensuing conflict claimed some 30,000 lives.
