POLICE ISSUE TRAVEL ADVICE
Police have urged Londoners to carefully plan their journeys home after the bomb attacks in the capital.
Much of the public transport network is paralysed with the Tube network - which serves 3m people daily - not expected to be open again until Friday morning at the earliest.
Areas of the centre of the city remain closed to traffic to allow ease of access for the emergency services although mainline train services wre slowly returning to normal.
Many companies sent their staff home early and will remained closed on Friday due to the expected strain on public transport.
Andy Trotter, of the British Transport Police, said: "The transport infrastructure is facing challenging times.
"Overground stations King's Cross and Liverpool Street remain closed." He added Victoria is expected to open later on Thursday following a further bomb scare.
"We, along with the various agencies, are doing our very best to open up the system.
"Londoners should think about their journeys home, check if their services are still available and then try and make their way home.
"Try not to all leave at the same time - we do not want a rush."
One eyewitness had earlier described a "sea of people" making their way out of central London by foot.
A riverboat services on the Thames will be free to use for the rest of Thursday.
Charles Clarke, home secretary, said: "People should avoid making any unnecessary journeys into the centre of London."
All UK airports were running as normal although flights to Israel could experience delays due to extra security measures.
Heathrow Airport also warned passengers could experience delays later as an effect of the public transport shutdown in London.
A British Airways' spokeswoman said: "With the Underground suspended, passengers and staff will face difficulty getting to the airport and our flights may well be delayed."
The Gatwick Express, which runs out of London's Victoria station, is working normally, he added.
