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 the "nightmare".

"I would like to thank everyone who has supported us for your poems, your messages and posts that have so helped us. What are we going to do to start again, to bounce back?" she told reporters outside the bar, La Bonne Biere, in the east of the city.

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