The victims of the Paris attacks have been remembered during a special service at the city's iconic Notre-Dame Cathedral on Sunday night.

Thousands of mourners gathered both inside and outside the place of worship, which had been closed to tourists since the unprecedented attacks at multiple sites in the French capital at the weekend.

Throughout the Sunday evening service, the sound of sirens drowned out the tolling bell of the Notre-Dame Cathedral.

At least 3,000 mourners made it inside as thousands more live streamed proceedings on their cellphones outside.

Although French authorities had asked people to stay indoors in the wake of the attacks, Parisians defied the call and gathered at various locations in the French capital to pay their respects.

Heavily armed policemen stood sentinel in and around the vicinity.

At one point chaos and fear gripped the area as rumours of fresh gunfire did the rounds.
