A Paris bar where five people were killed by jihadist gunmen in the attacks three weeks ago became the first to re-open Friday after what its manager called a "nightmare".

"I would like to thank everyone who has supported us for your poems, your messages and posts that have so helped us," Audrey Bily told reporters outside the bar, A La Bonne Biere, in the east of the city.

"What are we going to do to start again, to bounce back? We have carried out some work, repainted the walls to wipe away the signs of this nightmare.

"The Bonne Biere cafe was a place where people meet and exchanged and shared. That is what we want it to be again today," she added, as a handful of customers returned to the bar for their morning coffee.

Piles of flowers and candles still line the pavement in front of the bar.

The Casa Nostra restaurant opposite the cafe, which was also hit, is still closed.

Four other bars and restaurants as well as the nearby Bataclan concert hall were also targeted in the November 13 attacks in which 130 were killed.

On Wednesday, two of the Bataclan's owners said they intended to reopen the venue -- where 90 people died in the deadliest of the attacks -- by the end of next year.

Hundreds of people still flock there every day and fresh flowers line the pavements outside.

Cleaning workers have also begun clearing away flowers from outside the Carillon bar and the Petit Cambodge restaurant, where 15 people lost their lives.
