London commuters on nervy return to work

Whereas commuters were largely defiant after the first attacks that killed 56 people, they betrayed traces of nervousness after Thursday's failed attacks on three Underground subway trains and a double-decker bus.

"Yes, I'm afraid. I always take the Tube (subway) to go to work but now I feel more confident with the bus," said Ehelena Osaki, 24, told AFP in the City financial district.

"The bus also is worrying me a bit but you've got to get to work, no? I'm too young to die."

News that police had shot and killed a man at an Underground subway station in south London on Friday will likely do little to calm nerves.

Commuters faced disruption on the sections of London's transport network, with two Underground lines closed and three running a restricted service. Several stations on other lines were also shut down.

Up on street level, buses were running a full service, but diversions were in place near two of the four sites of Thursday's incidents.

David Roberts, 29, who rode a bicycle to work, said that two incidents in as many weeks were "putting fears into people's minds".

"I wouldn't go in the Undergrou-nd with my two children. I would fear too much for their safety."
