Police operation in Saint-Denis, near Paris comes five days after the Paris terror attacks.
At least seven explosions have been heard at the scene of a police standoff with suspects in last week's deadly Paris attacks.
Associated Press reporters at the scene could hear what sounded like grenade blasts from the direction of the standoff in the heart of the Paris suburb of Saint-Denis.
The source of the blasts is unclear. Police say several people are holed up in an apartment and several police have been injured in an operation that has lasted at least three hours on Wednesday morning.
