Fires in Russia

There are 2 more fires since last night. Another in the same city that was some kind of agricultural storage facility. The second was a fire in another city and was a Russian military base. Video below is from the military base fire. None of these were small fires, they were all quite large and did significant damage. I can't help but feel like these fires are the work of saboteurs. With each new fire, it's hard to see it all as coincidental
