Three people have been reported dead amid shooting and explosions in Saint Denis, a northern Suburb of Paris, as French police are working to hunt down people suspected of involvement in last week's series of deadly attacks.

A woman has reportedly blown herself up during the hours-long police operation. According to police sources cited by CNN, a total of six suspects had been surrounded by police, three of them were killed and three arrested.

France's Justice Minister says the operation is coming to an end.

A series of explosions was reported. Information emerged of a civilian victim, but was not immediately confirmed.

Explosions have been heard at the site, and helicopters are hovering. Soldiers and police in riot gear can be seen all around the scene.

BFM TV footage, shown on CNN, suggests heavily armed police have surrounded two or three suspects in an apartment located in the suburb.

Saint Denis is also the district where one of the attacks, the one at Stade de France, took place on Friday evening.

The attacks of last week left 129 dead and hundreds wounded.
