Russia is trying to destabilise German society and the state with propaganda campaigns and cyber attacks, Germany's domestic intelligence agency said.

Salah Abdeslam, a prime suspect in the Paris attacks, had documents about the German nuclear research centre, Juelich. 

The head of Germany’s intelligence agency has said authorities now know of 550 people from the country who have travelled to Syria and Iraq to join extremist groups, about 60 of whom have died.
