MADRID (AP) — Police in Barcelona say they have evacuated two trains in the city's main station and are conducting checks for explosives after a suspicious suitcase was found.

A spokeswoman with the Mossos d'Esquadra regional police says the unit specialized in explosives was activated Wednesday morning at the high-speed railway tracks of Barcelona's central Sants station. Police say the station's security management identified an object shaped like a possible explosive device inside a suitcase at 8 a.m. Wednesday (0700GMT).

The spokeswoman, who wasn't authorized to be named in media reports, says police are following security protocol.
