Two people have been arrested in British Columbia accused of plotting to plant a bomb outside the provincial legislature on Canada Day.
The Royal Canadian Mounted Police said John Stewart Nuttall and Amanda Marie Korody were inspired by al-Qaeda.
The BBC reports they were arrested in the town of Abbotsford on Monday, which was Canada's national day. They are due in court later on Tuesday.
RCMP officers said on Tuesday said the pair were charged with conspiring to place an explosive in a public place with the intent of causing death or serious injury and with possessing a device to cause an explosion.
Images of pressure cookers were displayed, which were reportedly to be used to make bombs similar to those detonated at the Boston marathon bombing in April.
The RCMP said that inside the pressure cookers were nuts, bolts, nails and washers.
