SLOVYANSK, Ukraine — A column of armored vehicles flying Russian flags drove into a Ukrainian city controlled by pro-Russian insurgents Wednesday, dampening the central government's hopes of re-establishing control over restive eastern Ukraine.
Still, it was far from clear just who these mostly masked men were and what their presence meant for eastern Ukraine, which has seen a surge of support for closer ties with Russia and against the new government in Kiev, which wants closer links to Europe.
Troops in camouflage sat atop the six vehicles as they entered the city of Slovyansk, a hotbed of unrest against Ukraine's interim government.
Insurgents in Slovyansk last weekend seized the police headquarters and the administration building, demanding broader autonomy for eastern Ukraine and closer ties with Russia. Their actions have been repeated in at least eight other cities in eastern Ukraine.
