TORONTO (Reuters) - A group of Canadian residents arrested for "terrorism related offenses" had amassed enough explosives to build huge bombs and were planning to blow up targets around southern Ontario, Canadian police said on Saturday.

Mike McDonnell, assistant commissioner of the Royal Canadian Mounted Police, said the group had acquired three tonnes of ammonium nitrate -- or three times the amount used in the 1995 bombing in Oklahoma City -- as they sought to "create explosive devices."
