A march in Ukraine's second largest city, Kharkiv, ended in bloodshed Sunday as a bomb blast tore through a crowd of people waving flags, killing at least two.
The attack came as people marched through a street to mark one year since former president Viktor Yanukovych was toppled from power, sparking a bloody civil war in the country in which Russian-backed rebels have claimed autonomy over swathes of Ukraine's east.
Among those killed was a police officer, according to Ukraine's interior ministry, while more than 10 other people were injured.
Officials said the explosive device may have been thrown from a car.
Government figures say four people have already been detained over the attack, according to the BBC.
These two YouTube clips show the moment of the blast and its chaotic aftermath. WARNING: Graphic footage.
A loud blast can be heard in the video, followed by scenes of people running for their lives.
Activists say the march continued elsewhere in the city after the blast.
