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.

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

But in the four days since, the tide of opinion in eastern cities appears to be turning back toward Kiev.
