Our correspondent recalls this major operation in detail:
I opened the window in the living room and leaned out of it, and then heard the shots. Then I ran to get my cellphone to film everything that was going on. I spent about two hours next to the window. Even when the battery ran out, I stayed there to keep watching.
There were moments of silence, and then there were moments when everything started once again. And then suddenly an explosion occurred that turned out to be a suicide bombing by a woman. I saw that blast on the third floor. It smashed the window, there was a flash, and after that a mattress fell out of the window. The firefight then started again, they were shooting from both sides.
I could see the arrest of two terror suspects. Then I saw them being followed by law enforcement, but it was night and it was hard to discern everything in detail. I also saw a policeman being taken away: his colleagues were supporting him as he was limping.
Earlier on Wednesday, French Interior Minister Bernard Cazeneuve confirmed that two terrorists suspected in Paris attacks had been killed and another seven detained during police special operations in Saint Denis.
Saint Denis is a densely populated northern suburb near the football stadium where two suicide bombers killed themselves and a bystander on November 13.
The attacks were followed by a series of mass shootings and suicide bombings at a concert hall and restaurants, killing 129 and injuring over 350.
