Russia sends troops to Armenian border with Azerbaijan after cry for help from Yerevan following altercations with Azeri forces — RT

 Armenia has confirmed reports that border guards from Russia have been deployed on the country’s frontier with Azerbaijan, as part of Moscow’s agreement with its allies in Yerevan to help bolster the Caucasian nation’s defenses.

Both Russia and Armenia are part of the Collective Security Treaty Organization (CSTO), a mutual defense pact, similar to the US-led NATO bloc, made up of six former Soviet republics.

The move comes a week after Armenian Prime Minister Nikol Pashinyan asked Moscow for assistance. A day prior, three of his countrymen were killed in a cross-border altercation with Azerbaijani forces – a battle that only ended when Russia stepped in with a ceasefire agreement.
