The CIA has warned counterparts in Europe of the possibility of terror attacks in several countries, with Paris' sewage system among the suggested targets, a French official said Thursday.
The US spy agency warned that al-Qaida agents may be planning suicide or bombing attacks in London and cities in Italy, France and Germany, Le Monde newspaper reported. It said the CIA had warned of the possibility of attacks taking place this month.
The French official confirmed to The Associated Press that such a note had been sent. The official said the CIA mentioned "waste water systems" in Paris as a potential target.
However, the warning didn't specify dates or exact sites that could be targeted, and no elements led French authorities to believe there was a concrete plot, the official said on condition of anonymity because of the sensitivity of the matter.
