Armenia reported Saturday that "fierce combat" with Azerbaijani forces took place overnight near the town of Shusha, a key stronghold in the disputed Nagorno-Karabakh region.
After weeks of heavy fighting over the mountainous province, Azerbaijan appears to be closing in on the strategic town, 15 kilometres from Karabakh's main city Stepanakert.The hilltop town of Shusha is located on a main road that links the unrecognised republic's capital with the territory of Armenia, which backs the separatists fighting for Karabakh's independence.
Armenian defence ministry spokeswoman Shushan Stepanyan reported "especially intensive and fierce combat" overnight outside Shusha, adding that numerous attacks from Azerbaijan were thwarted.
Armenia also said that throughout the night there was regular shelling on Shusha, home to a beloved Armenian cathedral that was damaged in attacks last month.
The Azerbaijani Defence Ministry rejected this claim saying the information of shelling on Shusha is "completely untrue".
A second Armenian army spokesman, Artsun Ovanissian, wrote on Facebook that there had been "no loss, no retreat" at Shusha and that "fighting continues".
Meanwhile Karabakh authorities said the territory's main city Stepanakert had been hit by Soviet-era Grad and Smerch rockets, although no-one was hurt.
Clashes broke out late September between Azerbaijan and Armenia-backed separatists over control of Karabakh, a region that proclaimed its independence from Baku during a war in the 1990s.
The recent flare-up has been the worst in decades, killing more than 1,000 people, including civilians, although the death toll is believed to be much higher.
The fighting has continued despite several attempts by Russia, France and the United States to help reach a lasting ceasefire.
Those three countries make up the Minsk group of mediators which helped broker a truce between the ex-Soviet rivals in 1994 but are yet to find a lasting solution to the long-simmering conflict.
French President Emmanuel Macron's office said Saturday that he had spoken with Russian leader Vladimir Putin by phone and agreed that "fighting must be stopped" in Karabakh "to allow negotiations to restart on a realistic basis".
Armenia and Azerbaijan have each accused the other of targeting civilian areas and the United Nations this week decried indiscriminate attacks that could amount to "war crimes".
