Police among dead, wounded in blast at Kharkiv, Ukraine, rally

Four people belonging to a group that received training in Belgorod, Russia, have been arrested, Secretary Oleksandr Turchynov of Ukraine’s National Defense and Security Council said on his website. A gun was also confiscated.

Though there were reports that someone threw an explosive device from a vehicle, the blast appeared to be caused by a remote-controlled device, Turchynov’s statement said.

Footage from the rally shows an estimated 500 people marching through a Kharkiv street, many hoisting Ukrainian flags, when the explosion sends rally participants and onlookers scurrying for cover.

Police and others rush to treat three people — two men, one in camouflage fatigues and another who appears to be in civilian dress, lying motionless on the ground and a third man in camouflage who seems to have suffered shrapnel injuries to his legs.

Ukraine’s National Defense and Security Council said Friday there had been 300 instances in which the latest truce was violated, and the news agency Ukrinform published a map Saturday showing how the eastern portion of the country is still racked by violence.

The ceasefire agreement — signed February 12 in Minsk, Belarus, among the leaders of Ukraine, Russia, France and Germany — aimed to curb this violence. It is supposed to be followed by the withdrawal of heavy weaponry to create a buffer zone, the release of prisoners and steps toward new elections.
