- There are different theories, including the one you mentioned. That theory cannot be ruled out. In any case, this tragedy is being used by pro-Western opposition in Armenia to stir anger.

 - I do not think so. Most Armenians realize that Russia is their only ally in the region. The withdrawal of Russian troops from Armenia can seriously complicate the situation in Armenia. And yes, Armenia may lose control over Nagorno-Karabakh in the future. Armenia has always had some anti-Russian forces. This is another matter. In Soviet times, Armenian separatists led by a certain Zatikyan carried out terrorist attacks in Moscow, killing people. They were captured, tried and executed.

- Right, I do not think Russia will withdraw from Armenia. In the short term, this incident will certainly complicate relations between the two countries. But key points of cooperation will not be affected. Unfortunately, it is impossible to be fully insured against tragic incidents like these. The leaders understand that.  If you have a large number of Armenian citizens or ethnic Armenians in Russia and Russian citizens in Armenia, some incidents are possible from time to time. The same applies to citizens from other countries.

- It is difficult to say at the moment. It is a question to be put to the authorities of the two countries. If found guilty, he will probably face the same punishment in both countries, that’s life in prison.
