Meanwhile, conspiracy theories flourish.

"I'm certain that the shootings of the 20th were carried out by snipers who arrived from Russia and who were controlled by Russia," says Andriy Parubiy, the former Commandant of the Maidan.

"The shooters were aiming to orchestrate a bloodbath on Maidan."

This is a widely-held belief in Ukraine. In Russia, many believe the opposite - that the revolt on Maidan was a Western conspiracy, a CIA-inspired coup designed to pull Ukraine out of Moscow's orbit. Neither side offers convincing evidence for its assertion.

The overwhelming majority of the protesters on Maidan were peaceful, unarmed citizens, who braved months of bitter cold to demand a change to their corrupt government. As far as is known, all the protesters killed on 20 February were unarmed.
