Hundreds of French security forces today converged on an industrial park northeast of Paris where Saïd and Chérif Kouachi, the suspects in Wednesday’s attack at magazine Charlie Hebdo, were barricaded with at least one hostage at a printing business, the New York Times reports. French police also responded today to a siege at a kosher supermarket on the eastern edge of the capital where two people had been killed and at least five taken hostage by suspect Amedy Coulibaly, who was believed to have joined the same jihadist group as the Kouachi brothers.
