Dr. Olga Bogomolets, a well-known physician and the head doctor for the anti-government protest movement, confirmed the death of three protesters. The clashes come almost one month to the day of a battle between police and protesters on another central street, Hrushevskoho. From Jan. 19 to Jan. 23, the two groups fought around the clock. At least five protesters were killed as a result, and several hundred on both sides were badly hurt.

On Tuesday, more than 1,000 protesters went back to the street and reinforced barricades erected in January. There, they burned tires to create a smokescreen and keep police from advancing. The public unrest in Ukraine began last November, when President Yanukovych spurned a long-anticipated deal with the European Union, and instead turned to Russia for a$15 billion bailout. Russia seeks to pull Ukraine into its political orbit, while the EU would like to see the former Soviet country move westward.

By nightfall, many thousands of protesters had converged on Independence Square, the heart of the Euromaidan protests since November. Fires were stoked with tires and Molotov cocktails. Below is a live video feed from the square, provided by Espresso TV:
