“The men who attacked the pro-Kiev rally Monday evening wore black masks and wielded clubs while announcing their allegiance to Russia. ‘They shouted, ‘If you don’t throw away your flags, we’ll kill you. This place is Russia, not yours,’ ’ said Olga Styagunova, 43, a marcher who ducked into a bakery to escape attack. The fate of Kharkiv’s mayor, who was shot in the back while out exercising, suggested that the separatists make good on their threats.”
