President George W Bush arrived in New York tonight to survey the carnage of Tuesday’s attacks on the World Trade Centre.
Security was tight as the President met rescue and emergency workers at the scene of the disaster where the twin towers of the World Trade Centre once stood.
He was flown to a New Jersey air base in the presidential plane Air Force One this evening.
Three days after the attacks, just a handful of survivors have been found in the twisted rubble of the collapsed buildings and fewer than 100 bodies have been recovered, of which only 30 had been identified.
Hopes were receding that any other survivors would be recovered from the wreckage.
New York Mayor Rudolph Giuliani said there was still hope of finding many more survivors, and President Bush said he was calling up 50,000 members of the National Guard and Reservists to help with recovery and security efforts.
