At least two people, including a police officer, have been killed after a bomb was detonated at a patriotic rally in Ukraine’s second city Kharkiv.
A bomb has killed at least two people, including a police officer, and injured 10 other people at a patriotic rally in Ukraine’s second city Kharkiv.
The device exploded at 13:20 (11:20 GMT) as people gathered near the city’s Palace of Sport for a march in support of national unity, Ukrainian media say.
Security forces have detained several suspects in the attack, officials say.
Kharkiv lies outside the conflict zone in eastern Ukraine, where a ceasefire appears finally to be taking hold.
The government and rebels there have agreed to start pulling back heavy weapons from the frontline, with the actual withdrawal expected to get under way on Tuesday.
The process will not be completed until at least 8 March, five days later than the deadline set at peace talks in Minsk this month.
Another key element of the Minsk deal moved forward on Saturday when the Ukrainian government and the rebels exchanged 191 prisoners.
An unnamed regional prosecutor, quoted by Reuters news agency, said an explosive device had apparently been thrown from a car in Kharkiv.
A photo apparently taken at the scene shows a body draped in a Ukrainian flag as ambulances stand nearby.
Another image shows people gathering around an injured person.
“Ukraine’s security service detained persons who may have been involved in the preparation and carrying out of crimes of a terrorist nature in Kharkiv, including the explosion,” security service spokesman Markian Lubkivskyi wrote on his Facebook page.
Before Sunday’s explosion, Kharkiv, in the north-east of Ukraine, had seen more than a dozen attacks over three months, including an explosion in a bar used by pro-government activists which injured more than 10 people in November.
That attack was blamed on a pro-Russian group calling itself the Kharkiv Partisans.
