Days after coordinated attacks in Paris that killed at least 129 people, residents of the French capital returned to work in a sombre mood.

Schools reopened and train stations were packed with commuters on Monday (16 November), but flags flew at half mast and newspaper headlines focused on the repercussions of Friday's bloodshed.

People living and working in Paris said they were finding it hard to get on with life as normal after the attacks.

"Resuming everyday life is certainly very difficult, but we do it with an almost stronger will. We have understood that terrorism exists to frighten us, and that's exactly what we need to fight against. We have been talking about a war, and indeed the events do look like acts of war, and I think we need to challenge this fear," said one citizen.

"We are not the same as we were before Friday. We are all tormented by the number of victims, the number 130 (dead), I keep running that number in my head again and again," said another.

At 12 pm, Parisians and the rest of France fell silent for a minute to remember the victims.

President François Hollande has declared three days of national mourning and the state of emergency calling the attacks an "act of war".

He will address the Congress in Versailles today at 4 pm. The first time since 2012, confirming the government's will for an extraordinary response to the attacks.
