French police stormed a printing plant north of Paris on Friday, freeing a hostage and killing two brothers linked to al-Qaida who were suspected of slaying 12 people at a Paris newspaper two days ago. Also in Paris, two police officials say at least four people, including the attacker, have died at a kosher grocery in Paris where a gunman took several hostages. Security forces stormed the grocery minutes after their counterparts assaulted the building outside Paris where two brothers suspected in the Charlie Hebdo killings had holed up. The two police officials, who could not be named speaking about the quickly developing situation, confirmed the attacker died. One of the officials said three of the dead were hostages.
