Canada's police arrested 10 young people at Montreal's Trudeau International Airport on suspicion of planning to travel to Syria to join Islamic State (Isis). The Royal Canadian Mounted Police (RCMP) said that the passports of the 10 suspects had been seized.

"No charges have yet been brought," said the RCMP in a statement, "and the identities of those arrested have not been revealed. We can say, however, that the families and friends of the young persons have been met by investigators.

"These are very difficult times for the relatives and loved ones of the persons arrested, as the decision to leave the country was not that of the family, but of a single family member. As a result family members often find themselves at a complete loss and unable to understand the decision made by the youth."

Some are believed to have ties to six young people, including two teenage women from Quebec, who allegedly travelled to Syria through Turkey in January, reports CNBC.

The RCMP's specialised anti-terror unit, Quebec's provincial police and the Montreal police all took part in the operation.
