Estona and Russia clash.
The Estonian Government removed a statue called the "Bronze Soldier" from the Talinn square where it had stood for 60 years, the statue is a memorial to Red Army soldiers who died. The Estonian ambassador was attacked in Moscow by a group called Nashi which is backed by the Kremlin. Estonians claim that not enough was done to prevent the attack. Estonians don't like the statue claiming it is a reminder of 50 years of Soviet occupation and Russians like the statue because it is a reminder of Nazi liberation of Northern Europe.
The challenge for this story is the scandal surrounding how much was done to prevent the Russian youths from attacking the Estonian Ambassador. All the reporter can do is get statements from both sides, maybe the reporter knows more but wouldn't be able to offer a firm conclusion. This could be one of those incidents where everybody kind of knows what happened, but no one will admit it.
It seems the plot thickens, I compared this story with one published in the Washington Post but written by Reuters. It seems that Russia may postpone delivery of oil products to Estonia. Russia claims disruption may occur as maintenance projects get underway on rail lines. This story mentions a rumor that Russia has in the past used energy resources as a political weapon.
This is a complicated issue, but I don't think there is much that Estonia can do. I can understand why Russians are angry over the relocation of the statue, but its not like Estonia destroyed the statue. It was relocated to a military cemetery on the outskirts of town. The disruption of oil products at this point seems a little too convenient. The EU is going to have to step in before this gets even uglier.
