PARIS, Dec. 28 (Xinhuanet) -- French security forces will be mobilized to try to prevent any acts of violence on the New Year'sEve.

    On the eve, 4,500 police and paramilitary gendarmes, backed by helicopters, will patrol Paris under strict orders to "prevent andrepress any acts of violence", the capital's police department said in a statement released on Wednesday.

    Sales of petrol in jerrycans have been banned before Christmas in several parts of the country over the end-of-year period, and will be banned in Paris from Friday.

    Paris region where hundreds of thousands of people gather on the New Year's Eve (500,000 on the eve of 2005), especially on the Avenue Champs-Elysees, will be closely watched.

    Public transport in the Paris region will be highly supervised to follow travelling of potential troublemakers towards Paris or between sensitive departments.

    Identity checks or arrests of offenders will be made wherever necessary in the Paris region, which will be under increased surveillance by hundreds of video cameras installed permanently in subways or in the streets, according to police.

    According to the police department, there is a threat to "public order in the capital" from people travelling from the areas around the capital, hit last month by an urban violence leaving nearly 10,000 cars torched.

    A state of emergency imposed in response to the rioting, allowing local governors to declare curfews and giving wider powers to the police, remains in place until February.

    Some 330 cars were torched across France last December 31. Enditem
