Two people have been killed, French media reported. France’s Ministry of the Interior formally denied reports that two people died in the kosher supermarket attack, France 24 said.

Police have completely locked down the area at Porte de Vincennes, RTL radio said.

“Panic at Porte de Vincennes. Policemen in bulletproof vests are evacuating everyone. The operation is underway,” tweeted Raquel Garrido from France’s Left Party.
