The Moscow metro is taking measures to step up security across all its routes. The announcement comes after bomb attacks on the London underground over a week ago left more than 50 people dead. With cameras placed in every carriage, the new controls will allow police to access a metro-wide communication system. The Moscow metro spans some 265 kilometres and is used by nine million people everyday. The system should be in place by 2007. The head of the Moscow underground said it would help stop people from laying explosives with timer devices in carriages, but would do little to protect passengers from suicide bombings.
