A man armed with a shotgun walked into the lobby of the French daily Liberation in Paris and fired twice Monday, the newspaper said.
A 27-year-old photographer's assistant was shot twice near the heart and is in intensive care, Paris prosecutor Francois Molins said.
Paris police had no information about the man's motive. He fled after the attack.
Later, a man opened fire in front of Societe Generale towers in Paris, the international bank said on Twitter.
