Paris mayor Bertrand Delanoe has been given extra security protection after an Islamist website used by Al-Qaeda members listed him as a target, police said on Wednesday.
A police source said Delanoe's protection had been "slightly reinforced", although he said the "threats are not specific and do not come from a site linked directly to Al-Qaeda."
The Socialist mayor, who is strongly tipped for reelection in March, said he was informed on Saturday of the threat, picked up by a US agency that monitors Al-Qaeda messages on the Internet.
It lists Paris and its mayor as targets for attacks, with the aim of provoking the downfall of President Nicolas Sarkozy. "We are adapting to the situation, without losing our nerve, without overly worrying," Delanoe told French radio RTL. One of France's few openly gay politicians, Delanoe was stabbed in an anti-gay attack in 2002.
