This raises some serious questions as to the motivation behind this spate of terror attacks. Ukraine, of course, is neither a member of the EU nor of the EEA. There is a division between Russian and Ukrainian cultures in Ukraine. It is worth people being aware that there are people whose objective is to cause division. The people who oppose violence and division need to stand together against people like the murderers of Lee Rigby, the EDL and others who wish to create division and strife.
Noting later that a further arrest has occurred it raises yet further questions. Ones which, over time, will be answered - however.
