"The schools were searched for suspicious objects, but none were found," the Aalen police, in southern Germany, said in a statement.

Schools had been a main target of bomb threats in the past days but Berlin's main train station and a radio station in Weimar city were also targeted

"The threats are almost certainly part of a (planned) series," the authorities said. The police forces are conducting a large-scale criminal investigation to find the perpetrators.

Also on Friday, the city hall in Erfurt, the capital of Thuringia, had to be closed off due to a bomb alert. 

A police spokesperson told the local media that the threat had been received by email, without giving further details about a possible motive.

Schools had been a main target of bomb threats in the past days but Berlin's main train station and a radio station in the city of Weimar were also targeted. It appears that the threats were mostly sent by email, but a lot of details are still unclear.
