Canadian police have arrested at least eight people in an anti-terror operation in the Toronto area.
The detainees are being held in Pickering, a suburb of the country's biggest city.
A police spokeswoman said that about 400 police officers had taken part in the operation, adding that more arrests were expected.
The Royal Canadian Mounted Police (RCMP) said it had made the arrests for "terrorism-related offences".
Corporal Michele Paradis, a spokeswoman for the RCMP, said the operation was ongoing.
However she declined to comment on the nature of the charges against those detained.
The Toronto Star newspaper said police had raided 12 locations in the area on Friday night to arrest members of what was described as a "homegrown terrorist cell".
Canada's Security Intelligence Service is said to have been monitoring the group since 2004, according to the newspaper.
