Hollande leads day of mourning in Paris

Today French President Francois Hollande will lead a service of commemoration for victims of the Paris terrorist attacks.

Under the famous gold dome at Les Invalides monument, more than 1,000 will attend the ceremony including families of the 130 victims and some of the 350 wounded, along with medical staff who cared for them.

The President will be joined by Prime Minister Manuel Valls as well as former president Nicolas Sarkozy and - controversially - National Front leader Marine Le Pen.

Maybe it will bring a bit of closure to the French people, that's what we need

– Journalist Clovis Casali, who lives in Paris

What motivates young extremists?

I left the project feeling hopeful... It's possible to be that extreme and that far gone and turn around

– Deeyah Khan

As the national ceremony takes place to remember those who died in the Paris attacks, many people will be asking what drives extremists to kill people.

We speak to documentary maker Deeyah Khan who has spent two years talking to disenfranchised young men to understand their motivation.

In the making of her film Jihad, Deeyah spent two years with some of the most influential and controversial figures in the British and Western jihadi movement of the past three generations. She meets one of the founding fathers of the British jihad, Abu Muntasir, who went abroad to fight, and who promoted extremism to thousands of young Muslims across the UK and the West. Now a reformed and moderate imam, he is tormented by his violent past. He fought in Afghanistan, Kashmir and Burma, and organised arms shipments.
