Pro-Unity-Rally in #Donetsk was sad to watch. >1000 peaceful protesters attacked by ≈100 youngsters. Several injured. Police did nothing

Media reports said dozens of men dressed in military fatigues and wielding baseball bats and iron bars attacked the rally of some 2,000 people.
Blasts were heard. City officials said that, according to preliminary information, at least 14 people were injured. Correspondents said many of the victims had head injuries.
Some reports said the assailants were shouting "Russia, Russia!" as they attacked the rally.
The demonstrators scattered after the violence broke out, with assailants reportedly chasing protesters down side streets after the rally dispersed. Reports said police attempted to hold the pro-Russia militants back but then largely stood aside as dozens of protesters were beaten.
Donetsk is one of string of cities in eastern Ukraine where pro-Russia separatists have seized government buildings.
Today's deployment brings to 600 the number of troops sent by Washington to Poland and the Baltic states to allay the concerns of eastern NATO allies over the escalating crisis.
Also today, Britain and France deployed eight fighter jets to reinforce NATO patrols over Estonia, Lithuania and Latvia.
Four British Royal Air Force Typhoon fighters landed in Lithuania, while four French Rafale jets landed in northern Poland.
NATO announced this month that it would step up its defenses in Eastern Europe due to the growing crisis in Ukraine and Russia's annexation of Crimea.

Most worrying thing about violence in #Donetsk today was the police refusal to restrain pro-Russian thugs. Clear whose side they are on.

Pro-unity rally (c300) attacked Donetsk by masked men. Clashes/injuries and the democratic space in eastern #Ukraine is closing

@GrahamWP_UK @zerohedge That's an extraordinary claim, Graham. Was perfectly peaceful until charged by dozens of club-wielding thugs.

@RolandOliphant now they're attacking cars near the cathedral. Think this is turning into a good old fashioned aimless rampage.
