Friday prayers held next to "Je Suis Charlie" banner

Muslim worshippers undertook Friday prayers in the eastern city of Saint-Etienne next to a banner reading "Je Suis Charlie," the slogan that has united much of the condemnation for Wednesday's attacks.

The rest of the banner reads "They want to snuff out the stars. We want to rekindle them!"

Earlier, hundreds of Muslims in the eastern city of Strasbourg held a minute's silence outside the Grand Mosque.
