Armenia called on the UN's top court on Wednesday to order its archrival Azerbaijan to withdraw a blockade from a key road connecting Yerevan to the disputed Nagorno-Karabakh enclave.
On April 23, Azerbaijan set up a roadblock at the entrance to the Lachin corridor, the only road linking Armenia to the separatist region.
Before that, Yerevan had already accused Baku of blocking the vital artery for nearly six months.
On February 22, the UN's top judicial body, the International Court of Justice (ICJ), ordered Azerbaijan to ensure free movement on the road, which is vital for supplying the population of Nagorno-Karabakh.
The region is populated mainly by Armenians who broke away from Baku with Yerevan's help.
Armenia asked the ICJ to order Baku to "withdraw any and all personnel deployed on or along the Lachin Corridor since April 23, 2023," the court said in a statement.
Yerevan also asked the ICJ to order Azerbaijan to "refrain from deploying any such personnel on or along the Lachin Corridor".
Baku's decision to install the blockade in April was seen as a further escalation of tensions between the two former Soviet republics, which have been at loggerheads for more than 30 years and fought two wars in the early 1990s and 2020.
Russia sponsored a ceasefire agreement that ended hostilities in 2020 and has deployed peacekeepers there.
The Armenian army said last week that a soldier had been shot and killed by Azerbaijani forces.
An Armenian and an Azerbaijani soldier were killed the previous week in other clashes.
Both former Soviet republics have appealed to the ICJ, which sits in The Hague, to intervene in the dispute.
In December 2021, the court ordered the two countries to avoid aggravating their dispute.
The ICJ rules on disputes between states, but while its decisions are final, it has no power to enforce them.
