“Al-Qaeda is plotting attacks on Europe’s high-speed rail network, German mass circulation daily Bild reported, citing intelligence sources. The extremist group could plant explosives on trains and tunnels or sabotage tracks and electrical cabling, said Bild. Bild said the information came from the National Security Agency (NSA) in the United States, which had listened in to a conference call involving top Al-Qaeda operatives. The attacks on Europe’s rail network was a ‘central topic’ of this call, Bild said. Authorities in Germany have responded to the threat with discrete measures such as deploying plain-clothed police officers at key stations and on main routes.”
