Today some barrage of Grad rockets was fired on an eastern suburb of Mariupol, a city in the south east of Ukraine and in the hands of the Ukrainian government. The 400,000 strong population of the city is believed to be in favor of the federalists fighting against the Ukrainian coup government. Last year it overwhelmingly voted (vid) to leave Ukraine. Some 30 people, all civilians, died in today's attack. There was no military target nearby. Whodunnit?
In September 2014 Hromadske TV, a new Ukrainian TV station financed by George Soros and the U.S. government, interviewed (vid) a former Ukrainian general Colonel General Vladimir Ruban. According to the provided translation he lauds the Ukrainian artillery which at that time shelled Donetsk from the airport but says that this just welds the people in Donetsk together. "They understand they are being shot at. It's one thing if attack groups or any mobile mortar troops drive through the city and shoot because you could say that this is just a sort of provocation by a third party. But if the artillery units fired from the airport then no one can claim that the separatists shoot themselves."
Two days ago a mortar attack on a bus in federalist held Donetsk which killed 13 people was likely done from within the federalists held city. While the Ukrainian government claimed that the federalists had themselves shelled the city they hold this seems quite unlikely to me. The Russia supported federalist later claimed that ten groups of Ukrainian partisans had infiltrated the city and that eight of those had been caught. This would fit the operational design earlier laid out by the former general.
Today's attack on Mariupol has no discernible military purpose. It makes absolutely no sense for the federalists to shell civilians in a city that is believed to be favorable to them. There is no clear evidence from where the shells were coming. The Ukrainian government claims the federalists did it while the federalists said they have no artillery nearby that could have reached the city and blame the coup government for the attack.
Today's attack is already used by hardliners to call for more European sanctions against Russia. Such sanctions would have no effect on Russia's position and are to the disadvantage of Europe. Only the U.S. and other hardliners who want a wider conflict with Russia would benefit form these.
In light of the mindset demonstrated by the former general and after the attack in Donetsk I tend to believe that this attack was a planned provocation by the Ukrainian side.
