A manhunt has been launched in Paris after a gunman attacked offices of the newspaper Liberation and fired outside the headquarters of the bank Societe Generale.
A photographer, 27, was seriously hurt at Liberation. The gunman later forced a motorist to drive him to the Champs Elysees before allowing him to go.
Police are looking for the same man who broke into the Paris offices of the 24-hour news channel BFMTV on Friday.
Police have now been stationed outside all the main media offices in Paris.
People have been encouraged to stay indoors. Police say the suspect is calm and assured, our correspondent reports, and each time has walked away from the scene of his attacks.
French media say the suspect told the motorist he hijacked that he was armed with grenades.
At 10:15 local time (09:15 GMT) on Monday, the gunman entered the Paris offices of Liberation, near the Place de la Republique in the east of the city, and opened fire.
He injured a photographer in the chest and stomach before escaping. Liberation said three spent cartridges had been found.
The gunman did not say anything during the attack, Liberation reported.
Some two hours later, the bank Societe Generale confirmed that a man opened fire outside its headquarters in the western business district of La Defense. No-one was injured, the bank said.
One witness of the bank shooting told Le Figaro that he heard a large bang and saw a man wearing a khaki coat and a cap and carrying a shotgun. (BBC)
