Ukraine police have said that at least 25 people have been injured after four bombs were placed in rubbish bins and set off in the Ukranian city Dnipropetrovsk.
The first blast occurred at a tram stop at 11.50am on Friday, injuring five people. The second explosion came 30 minutes later next to a cinema, injuring seven people, the emergencies ministry said in a statement.
Dnipropetrovsk was meant to be a host city for Euro 2012 but was replaced by Kharkiv back in 2009.
There was a third and fourth blast shortly afterwards in a park and in the downturn area of Dnipropetrovsk, though the number of injured from those explosions is, as yet, unclear.
“No-one has been detained yet,” a police spokesman said. Authorities offered no immediate explanation or any motive or say who they thought could be behind the bombs.
Bomb attacks have been rare in the former Soviet republic which will co-host the European football championship in June and July. But political tension is high because of the detention of Ms. Yulia Tymoshenko who was jailed for seven years last October for alleged abuse-of-office which she denies.
Should the Republic of Ireland finish as runners-up in the group phase, they will play a quarter-final in Kiev, 400km from Dnipropetrovsk. Many England fans are based in and near the city.
