Bomb attack on UK migrant centre

British police said yesterday that evidence revealed ‘‘an extreme right wing motivation’’ behind an attack last week at an immigration centre on the English coast, describing it as ‘‘a terrorist incident.’’ A 66-year-old man threw at least two petrol bombs at the walls of a migrant centre 30 near Dover, a point of arrival for many who attempt the journey across the English Channel in small boats. The assailant was later found dead. Authorities identified him as Andrew Leak. British counterterrorism police said they found evidence indicating the man was ‘‘motivated by a terrorist ideology’’.
