Street artists give Kiev colorful makeover

In a mural splashed across a four-story building in central Kiev, a small boy nonchalantly throws paper planes.

The peaceful image is just one example of the colorful street art springing up across the Ukrainian capital, reflecting a new mood of optimism in a city once criss-crossed by barricades.

The artist, 28-year-old Oleksandr Korban, is a former miner who fled the armed conflict in the separatist Donbass region of eastern Ukraine.
