Eastern European mercenaries suspected of stabbing Iranian journalist in London

Exclusive: police believe attack on dissident journalist was latest example of Tehran hiring criminal proxies to assault its critics in west

Three suspects wanted for the stabbing of an Iranian dissident journalist on a suburban London street were from eastern Europe and were hired and flown into Britain to carry out the attack, investigators believe.

Pouria Zeraati survived being stabbed in the leg in Wimbledon, south-west London, last month. His television channel, Iran International, had received threats before, which he and supporters blame on the Iranian regime.
