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

Today's S & P decision, downgrading the Russian companies to a notch above junk rating followed an earlier announcement from the United States that it was imposing new sanctions on Russian officials, including Rosneft CEO Igor Sechin.
Rosneft shares dropped more than 1 percent after the news was reported.
Sechin later dismissed the U.S. sanctions against him saying it would not harm his company's cooperation with foreign partners, including U.S. companies.
British energy group BP said today that it remained committed to its investment in Rosneft despite the sanctions.
The sanctions apply only to Sechin but analysts said the measures could hinder Rosneft's activities.
