Here are today's key developments:
Francois Hollande speech
- The French president said he would table a bill in the coming week to extend France's state of emergency to three months.
- He called for changes to the French constitution to allow French nationals to be stripped of their citizenship if they were convicted of terror offences.
- He pledged significant additional resources and personnel to French security forces.
- He vowed to intensify air strikes against Islamic State in Syria.
- French prosecutors identified Moroccan-origin Belgian Abdelhamid Abaaoud as the mastermind behind the Paris attacks. Abaaoud is thought to be in Syria.
- Prosecutors also identified one of the attackers as Ahmad Almohammad. Almohammad, a Syrian passport-holder, reportedly entered the EU via Greece along with refugees.
- Two of the seven people arrested in Belgium on Saturday were charged with terror offences. Five have been released, including a brother of two of the suspected assailants.
- Mohamed Abdeslam, whose brother Brahim blew himself up and whose other brother Salah is wanted by police, said he had no idea where Salah was and no advance warning of the attacks.
- French police are still hunting for Salah Abdeslam, thought to be one of the gunmen. Reports he had been detained during a raid in the Belgian town of Molenbeek turned out to be false.
- Italian police were alerted to look out for a black Seat car thought to be connected to the attacks that may have crossed into Italy.
The fight against Islamic State
- Francois Hollande called the attacks an "act of war" and vowed to "destroy" IS.
- IS issued two new propaganda videos from Iraq, celebrating the attacks in Paris and threatening Washington DC.
- US President Barack Obama ruled out sending in US ground troops to fight IS in Iraq and Syria. Mr Obama called the attacks "a sickening setback" but said the US would "intensify" air strikes.
- The Pentagon said it would step up intelligence sharing with France in the wake of the attacks.
