Paris attacks: Who was Omar Ismail Mostefai?
As French investigators continue to examine the events of Friday night, the only attacker to be formally identified so far is Omar Ismail Mostefai.
The 29-year-old French man was born south of Paris.
In recent years he had lived in the city of Chartres, south-west of the capital, and attended a mosque in nearby Luce.
BBC correspondent Matthew Price reports from there on what we know so far about Mostefai.
