EVER since the September 11 terrorist atrocity that devastated the heart of New York, the world has been in a heightened state of alert.

Last month's bomb attack in Madrid has only intensified the efforts to guard against further outrages.

Most days bring new stories to worry us. Today is no exception, with reports of ten suspected terrorists being held when police swooped on alleged Islamic extremists in Manchester, South Yorkshire and the Midlands.

Reports suggest that possible targets include the Trafford shopping complex in Manchester, and the football grounds of Manchester United and Manchester City.

Also today, news comes that British holidaymakers heading for the United States face a five-hour wait to check in. This new precaution is intended to allow time for airlines to file information to American authorities at least two hours before take-off.

Travellers will not be happy, but such delays are the price we pay for living in an understandably cautious age.

York has not such escaped, with the police stepping up terror patrols. Beat bobbies are forging closer links with British Transport Police officers patrolling York Station.

Importantly, this is just the sort of approach that is needed at such times. York Station has been aware of the potential of a terrorist attack for years and extra vigilance at the moment is vital. Co-operation between the police, the transport police and the management of the station is a key part of this strategy - along with the vigilance of the general public.

York Station was brought to a standstill for almost three hours in late December when armed police searched for the alleged police killer Nathan Coleman. That operation showed how well the different authorities can be mobilised in an emergency.

Such efficiency is a comfort these days.
