LONDON was brought to a standstill today as the terrorist bombs crippled the city's transport network.

Metropolitan Police Commissioner Sir Ian Blair warned people in the capital not to travel, but to remain in their offices or homes, while mounted police and other officers were overseeing the evacuation of people from office blocks and tube stations in the city centre.

Train services were disrupted, with many ending their journeys well short of London, and companies advised passengers not to try coming to the city.

Manish Dev, who recently moved to London from Childwall, said that the explosions had left the underground network in chaos. The 25-year-old financial reporting manager said: "The entire network is shut down. It's a nightmare as everywhere is closed."

Railway stations at Liverpool Street, Kings Cross, St Pancras, Marylebone, Euston and Stratford were closed, while roads were gridlocked as motorists tried to flee the capital.
