The operation to detain militants from the Right Sector radical Ukrainian organization, who opened fire and took hostages in the southern Ukrainian city of Kharkov, has been completed, the interior minister of the Kharkov Region, Anatoly Dmitriyev, said Saturday.

“Some 30 people have been detained. We are now counting the exact number. We will now establish their identities: they have no passports. We will take fingerprints from weapons that remain in the building,” Dmitriyev told an Itar-Tass correspondent.
