Fierce clashes left at least 30 Azerbaijani and Armenian soldiers dead Saturday as Russia and the West urged an immediate ceasefire after a major escalation in violence over the disputed Nagorny Karabakh region.
Armenian President Serzh Sarkisian said 18 Armenian troops were killed and some 35 wounded in the “largest-scale hostilities” since a 1994 truce ended a war that saw Armenian-backed fighters seize the territory from Azerbaijan.
Sarkisian did not specify if the troops were from the forces of unrecognised Karabakh -- which claims independence but is backed by Yerevan -- or Armenia’s army.
Earlier Azerbaijan’s defence ministry said that 12 of its soldiers were killed in the clashes and a military helicopter shot down.
The surge in fighting over the disputed territory reportedly also claimed the lives of one Armenian and one Azeri civilian after the arch foes accused each other of unleashing heavy weaponry across the volatile frontline.
Armenia accused Azerbaijan of launching a “massive attack along the Karabakh frontline using tanks, artillery, and helicopters” on Friday night.
Azerbaijan, however, insisted it had counter-attacked after coming under fire from “large-calibre artillery and grenade-launchers”.
Sarkisian said that clashes were continuing Saturday evening “in the north and south” of the frontline but insisted the “armed forces of Karabakh are in control of the situation.”
Ethnic Armenian separatists backed by Yerevan seized control of the mountainous Nagorny Karabakh region in the early 1990s war that claimed some 30,000 lives and the foes have never signed a peace deal despite the 1994 ceasfire.
The region is still internationally recognised as part of Azerbaijan and the two sides frequently exchange fire across the front, but the latest episode marked a surge in violence and sparked frantic appeals for peace from international powers.
Azeri forces claimed that they had taken control of several strategic heights and a village in the Armenian-controlled territory, but Yerevan denied the claim as “disinformation”.
- Ceasefire calls -
Russian President Vladimir Putin called for an immediate end to fighting along the frontline, the Kremlin said.
“President Putin calls on the parties in the conflict to observe an immediate ceasefire and exercise restraint in order to prevent further casualties,” Kremlin spokesman Dmitry Peskov told Russian news agencies.
Foreign Minister Sergei Lavrov and Defence Minister Sergei Shoigu held phone talks with their counterparts in Armenia and Azerbaijan to urge a de-escalation in the fighting.
Meanwhile, mediators from a group made up of representatives from Russia, the United States, France and the Organisation for Security and Cooperation in Europe (OSCE), which has been trying to negotiation a settlement, expressed “grave concern”.
The European Union’s foreign policy chief Federica Mogherini said that the reports of heavy fighting were “deeply worrying” and called on all sides to “avoid any further actions or statements that could result in escalation”.
Azerbaijan’s strongman President Ilham Aliyev also spoke by phone to ally President Recep Tayyip Erdogan in which the Turkish leader expressed “solidarity” with Azerbaijan, Aliyev press office said.
Energy-rich Azerbaijan, whose military spending has in the past exceeded Armenia’s entire state budget, has repeatedly threatened to take back the breakaway region by force if negotiations fail to yield results. Moscow-backed Armenia says it could crush any offensive.
The last big flare-up occurred in November 2014 when Azerbaijan shot down an Armenian military helicopter.
US Vice President Joe Biden met this week separately with both Aliyev and Sarkisian, as they attended a nuclear summit in Washington. He urged a peaceful settlement to the dispute.
Biden “expressed concern about continued violence, called for dialogue, and emphasized the importance of a comprehensive settlement for the long-term stability, security, and prosperity of the region”, the White House said.
