French police are probing suspected terrorism links after a 23-year-old soldier was stabbed in the throat outside Paris on Saturday.
Anti-terrorism investigators are combing through surveillance video for clues to the identity of the suspect and for any potential links to the recent brutal killing of off-duty British soldier Lee Rigby.
Several security cameras operated by public transport agency RATP and others captured images of the suspect both before and after the attack, a police official told the Associated Press on condition of anonymity.
"There are indeed elements that lead us to believe it (the French attack) could be an act of terrorism," Interior Minister Manuel Valls told France 5 television on Sunday.
"I won't say any more at this stage as the investigation is only beginning."
Police are hunting for a suspect who reports identify as a bearded man aged about 30, possibly of North African origin, who fled into a crowded train station after the attack.
The injured soldier, Cedric Cordier, remained hospitalized on Sunday but is expected to survive.

French police union UNSA spokesman Christophe Crepin told Reuters there were similarities between Saturday's attack and the brutal slaying of British soldier Lee Rigby on Wednesday.
"I think this person wanted to imitate what happened in London," he told Itele television.
Rigby was attacked and killed on the streets of the southeast London neighborhood of Woolwich in broad daylight by two suspected Islamic extremists.
One of the suspected attackers, Michael Adebolajo, was arrested in Kenya in 2010, where he was suspected of preparing to join terrorist group al-Shabab, the British Foreign Office said Sunday.
