French President Francois Hollande said a state of emergency would be declared across France and national borders shut following the attacks in Paris.
Mr Hollande said "several dozen" people had been killed in the attacks around the French capital.
He has called on people to stay "united and calm."
It is horror.
A state of emergency will be declared. The second measure will be the closure of national borders.
We must ensure that no one comes in to commit any act whatsoever, and at the same time make sure that those who have committed these crimes should be arrested if they try to leave the country
Mr Hollande added that he had asked for military reinforcements in the Paris area.
Samy Amimour, who was born in Drancy, a north-eastern suburb of Paris, is believed to be the first Paris attacker to be buried.
