A seven-hour long gun battle triggered by a French police raid against suspected Paris attack terrorists in the Saint-Denis suburb of Paris ended with two terrorists and a civilian being killed on Wednesday.

A woman suicide bomber blew herself up during the police operation and seven people were arrested, Reuters reported.

The raid was part of an intense manhunt for the alleged mastermind of the 13/11 attacks, the Belgian islamist Abdelhamid Abaaoud who, police believed, might have been in St. Denis, near to the soccer stadium which was site of one of the attacks that hit Paris last week.

Police raided an apartment in the Paris suburb of St. Denis seeking suspects in last week's attacks in the French capital in a pre-dawn swoop. Three sources told Reuters the raid stopped a jihadist cell that had been planning an attack on Paris's business district, La Defense, after coordinated bombings and shootings killed 129 across the city.

However, more than nine hours after the launch of the pre-dawn raid it was still unclear if they had found Abdelhamid Abaaoud although seven people were arrested in the operation, which started with a barrage of gunfire, including three people who were pulled from the apartment, officials said.

"It is impossible to tell you who was arrested. We are in the process of verifying that. Everything will be done to determine who is who," Paris prosecutor Francois Molins said at the end of the operation.

Local residents spoke of their fear and panic as the shooting started in St. Denis just before 4.30 a.m. (0330 GMT).

"We could see bullets flying and laser beams out of the window. There were explosions. You could feel the whole building shake," said Sabrine, a downstairs neighbor from the apartment that was raided.

She told Europe 1 radio that she heard the people above her talking to each other, running around and reloading their guns.

Another local, Sanoko Abdulai, said that as the operation gathered pace, a young woman detonated an explosion.

"She had a bomb, that's for sure. The police didn't kill her, she blew herself up...," he told Reuters, without giving details.

Three police officers and a passerby were injured in the assault. A police dog was also killed.

French Interior minister Bernard Cazeneuve told media after the raid that 'intelligence that led police to the apartment in Saint-Denis gave the impression that Abaaoud was likely to be there".
