Explosion in Ukrainian Court

Police in Ukraine are investigating an explosion at a court house in Kyiv. It is currently believed that a man, who had been in custody for eight years on charges of throwing a grenade during a demonstration outside the country’s parliament, killing three members of the National Guard and hurting more than 140 others in 2015, was responsible for the explosion. He was at the court to attend a hearing and it is being speculated that when it did not go the way he wanted he set off the explosion killing himself and injuring two police officers. 

It is unclear yet as to how he managed to get the explosives in the first instance, or how he got them in to the court.
