Are Russian officials involved in an assassination job in Berlin?

Germany has expelled two Russian diplomats over the killing of a Georgian citizen in Berlin.

Prosecutors suspect Russian or Chechen involvement in the attack.

Soon after the assassination of Georgian national Zelimkhan Khangoshvili in Berlin, suspicions arose that Russian intelligence services were involved.

The suspected killer is a 49-year-old Russian, currently in custody.

The assassination in Berlin could be similar to the poison gas attack carried out in Britain on double agent Sergej Skripal and his daughter in March 2017.

That prompted many western countries to impose sanctions on Russia.

The Russian government denies any involvement in the killing and is so far refusing to cooperate in the investigation.
