Nine people have reportedly been injured after an explosion on a tram in Dnipropetrovsk, in western Ukraine, according to Interfax. Those injured have reportedly suffered minor burns. The blast comes just six weeks after multiple explosions hit the city in what was deemed a synchronised terror attack. As many as 27 people were injured in the April explosions which targeted a cinema, a tram stop and the railway square. Ukraine is currently co-hosting the Euro 2012 football competition along with Poland, matches are being held in Lviv, Kiev, Kharkiv and Donetsk, Dnipropetrovsk is not a host city. UPDATE: The Regional Prosecutor has said that the explosion today has nothing to do with the April bombings. The Interior Ministry has claimed that the incident was the result of a 'mishandling of gunpowder'.
