Two men were have been arrested and charged with plotting a terrorist attack against a Canadian passenger train with support from al Qaida, police have said.
The Royal Canadian Mounted Police said that Chiheb Esseghaier and Raed Jaser, who live in the Montreal and Toronto areas, were conspiring to carry out an attack against Via Rail, but posed no immediate threat.
"It was definitely in the planning stage but not imminent," RCMP chief superintendent Jennifer Strachan told reporters.
Charges against the two men include conspiring to carry out an attack and murder people in association with a terrorist group.
Police said the men are not Canadian citizens, but declined to say where they were from. Police said the men had "direction and guidance" from members of al Qaida.
The investigation was part of a cross-border operation involving Canadian law enforcement agencies, the FBI and the US Department of Homeland Security.
There is no connection between the Canadian terrorist plot and the Boston Marathon bombings, said a US Justice Department official in Washington.
