巴黎警方正搜捕一名持枪歹徒
A manhunt is continuing in Paris after a gunman attacked offices of the newspaper Liberation and fired outside the HQ of the Societe Generale bank.
巴黎一位持枪歹徒袭击了《解放报》的办公室，并在兴业银行总部外开枪射击，目前搜捕行动正在进行中。
A photographer, 23, was critically 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.
At a news conference, investigators held up two images, one of the suspect in a street and another taken from BFMTV surveillance cameras on Friday.
Paris prosecutor Francois Molins said the "most likely possibility" was that a lone gunman was behind the three attacks and the hijacking. He said the suspect had not yet been identified and the motive was still unclear.
The man is said to be between 35 and 45 years old, between 1.7m and 1.8m tall (5ft 6" and 5ft 10"), with stubble（发茬，须茬） and greying hair.
Mr Molins said the suspect was wearing a black vest, a cap and white-soled green shoes.
The BBC's Christian Fraser in Paris says the gunman had walked into BFMTV on Friday morning and emptied the chamber of his gun in the reception area.
"Next time, I will not miss you," the man had said to an editor he threatened.
Our correspondent says that, for a time on Monday, a police helicopter hung over the Champs Elysees amid fears the gunman might be heading towards the Eiffel Tower, but it is speculated that he might have gone into the metro.
People were encouraged to stay indoors.
Police said the suspect was calm and assured, 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.
President Francois Hollande, who is in Israel, said the priority was "to stop an individual who had tried to kill and could try to kill again".
