France and its capital Paris went into lockdown on Friday night after a series of terrorist attacks left at least 40 dead, with the attackers still believed to be on the run.
Hollande held a crisis meeting late on Friday after reports of several shootings, a hostage taking at a concert hall and a suicide bombing near the Stade de France stadium, while France were playing Germany.
After the meeting Hollande announced that France's borders would be closed immediately, meaning effectively no one could leave or enter the country.
