Passengers travelling on the New York subway are subject to random searches from today.
The new security measure was announced hours after the incidents in London yesterday when attempts were made to set off four bombs on the city's bus and underground rail network.
With some four and a half million passengers using the New York transit system each working day, the threat of bomb attacks is seen as potentially deadly.
Mayor Michael Bloomberg admitted that passengers would be inconvenienced but said such security measures were now necessary.
