Canadian authorities have said they arrested terror suspects planning an attack on a commuter train. The arrests are unrelated to the Boston Marathon bombings.

Monday's press conference, held by the Royal Canadian Mounted Police (RCMP) in Ottawa, revealed that an investigation dating back to August 2012 had led to the arrests of two men. The FBI was involved in the investigation.

The attack was apparently going to target a commuter train in the Toronto area.

The suspects, who were arrested on Monday, were identified as Chiheb Esseghaier, 30, and Raed Jaser, 35, who lived in Montreal and Toronto, respectively. Neither man was a Canadian citizen, and police would not comment on their nationality.

The RCMP said in a statement that while the suspects had "the capacity and intent to carry out these criminal acts, there was no imminent threat to the general public, rail employees, train passengers or infrastructure."

The statement continued that the two men were facing charges that "include conspiring to carry out an attack against, and conspiring to murder persons unknown for the benefit of, at the direction of, or in association with a terrorist group."

Speaking at the press conference, RCMP Assistant Commissioner James Malizia said the two men had received "support from Al-QaIda elements located in Iran" in the form of "direction and guidance." Malizia added that there were no indications that the attacks would have been state-sponsored.

Both suspects are scheduled to appear in court on Tuesday.
