Canada police nab 10 on terror charges

At least 10 suspects were arrested in the Toronto area on terrorism-related charges, the Royal Canadian Mounted Police said.

The Canadian Press quoted an unnamed police source as saying the charges were related to an explosives plot in Ontario, Canada's largest province. The arrests were made throughout Friday and more were expected overnight, with some 400 officers involved, in cooperation with the Integrated National Security Enforcement Team, said RCMP spokeswoman Cpl. Michele Paradis.

The national police force said it would reveal more details at a news conference Saturday.

"The investigation is ongoing," Paradis said. "Most of the police services throughout the greater Toronto area have been involved."

The Integrated National Security Enforcement Team is comprised of the RCMP, federal agencies such as Canada Border Services Agency, Citizenship and Immigration Canada and the Canadian Security Intelligence Service, as well as provincial and municipal police services. Armed officers were surrounding the Durham Regional Police Station in the city of Pickering, just east of Toronto, as the suspects were brought in unmarked cars which were drove into an underground garage.

The arrests could be tied to investigations of two men skulking around a downtown Toronto subway stop with video cameras on May 23. Police said passengers reported the men were filming around the Keele subway stop and beneath subway car seats.
