Police in the UK are upping security at Christmas markets after the Berlin terrorist attack that killed at least 12 and injured some 49 people.
London's Scotland Yard said it will review security arrangements for Christmas and New year events in light of the Breitscheidplatz lorry crash and the Russian ambassador's death in Ankara.
Mancheser police meanwhile says it is increasing patrols at many of its popular Christmas markets and adding extra protection at 10 market sites during this festive season.
The force's assistant chief constable Debbie Ford said the increase was in line with Britain's "national response" and that there was no intelligence suggesting an imminent attack in Greater Manchester.
The country's terror threat has long been judged to be 'severe', meaning an attack is highly likely.
In a statement, the Metropolitan Police said it has "detailed plans for protecting public events over the Christmas and New Year period".
The Met said: "These already recognise that the threat level is at 'severe', meaning an attack is highly likely, and have considered a range of threats, including the use of large vehicles.
“As a matter of routine, as a precaution, we review our plans after attacks overseas, and we are doing so at present following the awful incidents in Berlin and Ankara last night.”
