German police, hunting for a Syrian-born man suspected of planning a bomb attack, found explosives in an apartment they raided while looking for him on Saturday, officials said.
Police appealed to the public to call them with any information on Jaber Albakr, 22, who was last seen in the eastern city of Chemnitz wearing a black hooded top with a bright pattern on the front.
Police detained three people in Chemnitz who they said were known to Albakr, but he remains at large.
The police deployment followed a tip-off from the domestic intelligence service, though the "where, when, how and why" of the planned attack remained unclear, said Bernhardt.
Police asked local residents to remain indoors and began evacuating more people after discovering the explosives. Bernhardt said it was unclear how many suspects might be involved.
