In an interview on RTL, Manuel Valls - the French Prime Minister - has warned that more terrorist attacks should be expected.

Terrorism can strike, has struck -- though we have avoided several attacks -- and could strike again, now, in the coming days, in the coming weeks. I am not saying that to scare people but just so everyone understands. Today, the French are going back to work after these awful days, children are going back to school, life has to go back to normal of course, but were living with, and were going to live for a long time, with this terrorist threat and we need to prepare ourselves for further attacks.

French President Francois Hollande declared a state of emergency on Saturday 14 November, calling the attacks an act of war.

Were using the possibilities given by the state of emergency. Administrative raids 24/7, and that means our police service can stop all those who are in the radicalised jihadist movement, added the French prime minister.

Troops numbering 1,500 have been deployed after a near-simultaneous series of explosions and shootings brought Paris to a horrified standstill overnight. Currently, the death toll stands at 129 with around 99 critically injured and 200 wounded, officials said.
