Information is emerging about some of the 129 people killed in the Paris attacks, while family and friends of those missing reach out via social media.
Islamic State has claimed responsibility for Friday night's attacks which killed 129 people and injured 352, with 99 people in a critical condition.
At least seven attackers opened fire and used explosive devices at seven locations across Paris, including a concert hall, restaurants, bars and outside a stadium.
About 89 people were killed and many more wounded at the Bataclan concert hall, where metal band Eagles of Death Metal were playing.
The band's merchandise seller Briton Nick Alexander was among those killed, the UK Foreign Office and his family have confirmed.
In a statement, his family said: "Nick was not just our brother, son and uncle, he was everyone's best friend - generous, funny and fiercely loyal.
"Nick died doing the job he loved and we take great comfort in knowing how much he was cherished by his friends around the world."
