A crowd stormed a police station in the town of Horlivka, near Donetsk, taking control of the building. Ukraine's interim president Oleksander Turchinov said on Monday the offensive against the rebels would still go ahead. The proposal was rhetorical as no such deployment has been proposed or could ever take place over Russia's Security Council veto.

 Russian President Vladimir Putin's spokesman told Interfax he had been "receiving many appeals from eastern Ukraine... calling on him to help in some form", and that he was watching developments "with a great deal of concern". Ukraine's foreign ministry said on Monday that it had proof Russian forces had been behind the "separatist operation" and said it would present its evidence at a meeting in Geneva later this week.
– Ukraine's interim president gave pro-Russia militants occupying government buildings in Slaviansk and other eastern Ukraine areas until this morning to get out, or be forced out by the Ukrainian military—and the deadline has passed without the militants leaving. So far, Oleksandr Turchinov has not sent in the army, but clashes between Ukrainian forces and pro-Russia gunmen on the outskirts of the city left at least one Ukrainian dead yesterday, the BBC reports. Today, at least 100 pro-Russia separatists attacked a police station in another eastern Ukraine city, Reuters reports. At yesterday's emergency UN Security Council meeting, Russia's ambassador urged the Ukrainian government to "start a genuine dialogue" with protesters in eastern Ukraine rather than using force, while Ukraine's ambassador accused Russia of being behind the "separatist operation" in the first place. If Kiev follows through on its threat to bring in the military, Russia, which has 40,000 troops on Ukraine's eastern border, could push back; the US has compared the events in eastern Ukraine to the ones that led up to Russia's annexation of Crimea. But the Wall Street Journal reports that Turchinov also said today he's open to holding a referendum on the possibility of giving certain regions more autonomy, which is one of the rebels' demands.
