Around 10,000 protesters crowded into the center of Ukraine's capital Friday night to demand the president's resignation after he shelved a landmark agreement with the European Union in favor of closer ties with Russia.
An estimated 2,000 police in helmets and riot gear surrounded the demonstrators on Independence Square. There were several small scuffles with police, but no major clashes into the evening.
Protests have been held in Kiev for the past week since President Viktor Yanukovych backed away from the agreement. Across town on Friday, another rally brought out thousands of people in support of the decision.
It was unclear how long the protests against Yanukovych would be allowed to continue. The square has symbolic weight as the iconic epicenter of the 2004 mass protests known as the Orange Revolution, which forced the rerun of a fraud-tainted presidential election. Yanukovych, the focus of those protests, is unlikely to risk allowing another such huge demonstration of discontent.
Opposition leaders who spoke to the crowd called for protests to grow.
