HARI SREENIVASAN: Paris is on high alert again, after a gunman killed one policeman and wounded two more, before being killed himself. The attack came just three days before voting starts in France’s presidential election.
The sitting president, Francois Hollande, said all indications are that it was terror-related. Authorities sealed off the area after the incident on the famed Champs Elysees. It happened near a subway station in an area popular with tourists.
