DONETSK, March 4 - More than 1,000 demonstrators with Ukrainian flags took to the streets of the eastern Ukrainian city of Donetsk on Tuesday, for the first time outnumbering pro-Moscow youths who have seized its government building, which flies the Russian flag, Reuters reported.

President Vladimir Putin's declaration on Saturday that Russia had the right to invade Ukraine was accompanied by pro-Russian demonstrations across Ukraine's mainly Russian-speaking south and east.
