PARIS - The Paris prosecutor says a lone gunman appears to be behind a shooting at a Paris newspaper office that gravely wounded a photographer, and three other attacks.
Francis Molins says the gunman opened fire at the prominent daily Liberation on Monday morning. Soon afterward, shots were fired at the headquarters of French bank Societe Generale west of Paris.
Police say that after that, a gunman took a driver hostage and made him drive to central Paris, before letting the hostage go.
Monday's events happened three days after a gunman threatened journalists at the BFM-TV news network.
Molins said Monday that "considering these four cases ... we believe a single gunman is the most likely possibility."
He said a motive for the attacks remains unclear.
