UN Secretary General Ban Ki-moon paid homage to the victims of the Paris attacks on Sunday with a visit to the concert hall and one of the bars targeted by the jihadists.

"I'm a Parisian and sitting on the cafe terrace," said Ban in French, evoking the "Je Suis En Terrasse" slogan of defiance used after the November 13 attacks.

He visited the Bataclan theatre where 90 people were killed and then had a coffee at La Bonne Biere bistro, where several customers were gunned down.

Ban described Paris as a "symbol of resistance" and was joined by Mayor Anne Hidalgo, who said the UN secretary general had asked to make the visit.

He is in Paris for climate talks that began last Monday.

The attacks, which left 130 dead, struck several bars and restaurants in eastern Paris, as well as the national stadium. Around 350 were wounded, many of them critically.
