Nagorny Karabakh - round 2?

[Feanor]

It looks a lot like the situation between Georgia and South Ossetia in the summer 2008 prior to the war. The ceasefire is being violated more and more frequently. And Russian media says that Azerbaijans tanks have been moving towards the border for two days now. Azerbaijan has also restricted access of journalists to the conflict zone. There have already been casualties from both sides.

I'm not sure how things will proceed, but it's very problematic because Armenia not only houses a Russian military base, but it's also a member of the CSTO, meaning Russia would technically be obliged to interfere. Has anyone gotten better info?

EDIT: In case anyone is confused. Armenia and Azerbaijan had a war in the 90s. Nagorny Karabakh is a region of Azerbaijan populated by Armenians. They pushed for independence in the 90s, and were backed by Armenia and Russia. Essentially Armenia won the war, gaining control of Nagorny Karabakh, and retaining it to this day though it's nominally independent. The conflict has been 'frozen' ever since, with Russian peacekeeping. It looks like it might be thawing.

Supposedly, the commander of Russia's troops in Armenia has said in case Azerbaijan resolves to force, the Russian military base may join in the conflict in accordance with Russia's obligations within the framework of the CSTO. That was last October.
I couldn't find the statement being explicitly confirmed or denied from higher levels, only that, at the meeting with his Azerbaijani counterpart, Sergey Shoygu said that it might have been a mistake on the journalist's side which resulted in distortion of base commander Ruzinsky's views.
