LVIV, Ukraine (Reuters) -Ukrainians paid tribute to prominent politician Andriy Parubiy as he was buried on Tuesday after being gunned down in a daytime attack on Saturday, the second assassination in the western city of Lviv in just over a year.
As mourners streamed across cobblestone streets, the motives behind the killing of Parubiy, who played a key role in a pro-democracy uprising in 2014 that ousted a pro-Russian president, and later served as parliament speaker, remained unclear.
