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 kilometers from Karabakh's main city Stepanakert.
The hilltop town of Shusha is located on a main road that links the unrecognized republic's capital with the territory of Armenia, which backs the separatists fighting for Karabakh's independence.
Armenian defense 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 an iconic Armenian cathedral that was damaged in attacks last month.
The Azerbaijani Defense Ministry rejected this claim saying the information of shelling on Shusha is "completely untrue.”
