Toronto (AP) -- Two men were arrested and charged with plotting a terrorist attack against a Canadian passenger train, police said Monday.

The Royal Canadian Mounted Police said Monday that Chiheb Esseghaier and Raed Jaser, who live in Montreal and Toronto areas, were conspiring to carry out an al-Qaida supported 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.

The investigation was part of a cross-border operation involving Canadian law enforcement agencies, the FBI and the U.S. Department of Homeland Security.
