Saudi intelligence services have warned of a new terror threat from al-Qaeda against Europe, particularly in France, Interior Minister Brice Hortefeux has warned.
He said the warning of a potential attack by al-Qaeda in the Arabian Peninsula was received "in the last few hours, few days."
European officials were informed that "al-Qaeda in the Arabian Peninsula was doubtless active or envisioned being active" on the "European continent, notably France," Mr Hortefeux said during a joint TV and radio interview on RTL-LCI-Le Figaro's weekly talk show.
The warning from Saudi Arabia is the latest in a series of alerts that have put French security forces and others in high-vigilance mode.
In September, Interpol warned an "Islamist threat on a world scale, and notably on the European continent," Mr Hortefeux said without elaborating. That was followed by another warning
of a woman suicide bomber who could take action in France — later judged not fully credible.
Intelligence sources in North Africa also contacted France about a potential threat as did the United States, he said. He said he had spoken at length with US Homeland Security Secretary Janet Napolitano.
It was the first time a French official has offered details about potential threats since mid-September, when officials first publicly invoked the possibility that France could be a target of radical Islamist groups.
"We must not overestimate the threat or underestimate it," the minister said. "We are directly concerned."
The US State Department advised American citizens living or traveling in Europe earlier this month to take more precautions following reports that terrorists may be plotting attacks on a European city, possibly a shooting spree or other type of attack similar to the deadly 2008 Mumbai attacks in India.
France began boosting security last month at busy tourist sites like Notre Dame Cathedral and the Eiffel Tower, which was twice evacuated after false claims of an attack. French authorities recorded nine bomb alerts in the capital in September, including the two at the Eiffel Tower — a three-fold increase from a year earlier. No explosives were found.
Speculation on the source of a potential terror threat has centered on al Qaeda in the Islamic Maghreb, another al-Qaeda offshoot active in Algeria and Africa's Sahel region, which took five French citizens hostage Sept. 16 from a heavily guarded mining town in Niger. Two workers from Togo and Madagascar also were captured.
