Police step up security in Jewish areas across London
Police have stepped up security in Jewish areas across London in response to the Paris attacks and increased tensions as the final edition of the French satirical magazine goes on sale across the city.
In Newham, east London, posters advertising a holocaust memorial event were defaced with words including "liars" and "killers", in incidents police are treating as hate crimes.
The mayor of Newham, Sir Robin Wales, said the incidents in east London were "despicable".
