The police operation to detain the two suspects in the Charlie Hebdo attack is underway Friday, with the three-day manhunt focused on a town 50 kilometres from Paris. The suspects are now surrounded and have reportedly taken at least one hostage.
The suspects - brothers Cherif Kouachi, 32, and Said Kouachi, 34 - are thought to have taken one hostage at a small printing shop in the town of Dammartin-en-Goele in the Seine-et-Marne region, around 12 kilometres (7.5 miles) from Paris' main airport Charles De Gaulle.
Shots were fired earlier on Friday north-east of Paris as police chased a car believed to contain the suspects, but there were no casualties.
The two brothers are suspected of killing 12 people at the Paris-based satirical weekly - eight journalists, two police officers, a maintenance worker, and a visitor. 11 people were also wounded - four of them seriously.
Nine people have so far been detained in the search for the brothers.
