Royal Canadian Mounted Police say two brothers have been arrested and charged with terrorism related offences.

In a statement police said that Ashton Carleton Larmond and Carlos Larmond, both 25, were planning to leave Canada to engage in terrorist activities abroad.

Police say Ashton Larmond is charged with facilitating terrorist activity among other charges.

Carlos Larmond faces charges of participation in the activity of a terrorist group and attempting to leave Canada to participate in terrorist activity abroad.

The news release says the arrests were made on Friday — Ashton Larmond was arrested in Ottawa while Carlos Larmond was arrested at Montreal's Trudeau international airport.

Police declined to comment further because the case is before the courts.
