A total of three people were injured in an explosion in an office block in Neckarsulm, a town in southwest Germany, on Wednesday.
The explosion was caused by a bomb in either a letter or a small parcel, a spokesman for the local police force in nearby Heilbronn told DW.
Around 100 people were cleared as police evacuated the building following the explosion.
Rescue workers are at the scene, along with members of state’s investigative police force for more serious crimes.
What happens next?
The police spokesman said officers were now searching for the perpetrator or perpetrators.
Second explosion in a row
On Tuesday, there was an explosion at the drinks production plant ADM Wild in Eppelheim, bordering the city of Heidelberg.
Tuesday’s explosion is believed to have been caused by a parcel bomb.
Eppelheim is 68 kilometers (42 miles) west of Neckarsulm. They are both in the German state of Baden-Württemberg.
