An explosive device was detonated near a court house during a hearing of a case involving a member of Ukraine's nationalist Svoboda party, Ukraine Today reports. 

Ukraine was earlier hit by a series of similar but smaller-scale incidents in other cities, and the country has tightened checks on transport in and out of the area of the government’s anti-terrorist operation and the Russian-occupied Crimean peninsula, as it believes potential terrorist threats could come from territories.
