A mobile phone found in Paris had a map of the music venue that was attacked by terrorists and a text message saying words to the effect of "let's go".

Confirming reports on French web site Mediapart and US television channel CNN, a source said the phone was found in a bin near the Bataclan concert hall where the bloodiest of the shootings took place on Friday.

At least 129 people died in the killings, including 89 at Bataclan.

Islamic State has claimed responsibility for the co-ordinated suicide bombings and shootings.
