"It is depressing that Armenia's membership in the CSTO did not deter Azerbaijan from aggressive actions," Armenian PM Nikol Pashinyan said.
In September, over 200 Armenian servicemen were killed in clashes with Azerbaijan.
The problem for Moscow is that it has believed that this area is its own backyard – what is known as a “near abroad” – but is seeing its grip weaken.
There are striking parallels between Israeli and Azerbaijani history that underscore the countries’ unique bond.
Both Armenia and Azerbaijan blame each other for the deadliest clashes between them since a six-week war over Nagorno-Karabakh in 2020 left thousands dead.
The announcement said the truce had been in effect for several hours. Armenia's Defense Ministry had earlier said that shooting in border areas had stopped.
Israel can use its leverage with Baku to pave a middle path between realpolitik and its values, becoming a stabilizing player in the South Caucasus.
Both the Armenian and Azerbaijani Armed Forces have reported casualties in the most recent clashes.
Azerbaijan said it had carried out an operation titled "Revenge" against a number of groups of Armenian forces in Nagorno-Karabakh.
It has been heart-breaking to observe how a religion that could be such a force for peace was instead distorted to justify heinous crimes.
