France has stepped up security around public buildings and transport fearing retaliation by Islamist groups after French military operations in Mali and Somalia.
A pilot was killed as air strikes were launched on hundreds of Malian rebels.
In Somalia, a French hostage is believed to have been killed during a failed raid to free him by French special forces. Two soldiers also died.
