British Prime Minister Tony Blair is calling for calm following explosions at three London subway stations and a city bus earlier today.
The British leader called the explosions an attempt to frighten Londoners and urged citizens to return to business as normal.
Service has been suspended on at least three subway lines. Armed police also entered a hospital near one of the incidents, cordoning off the building.
London's police commissioner Ian Blair said the situation in the city is now fully under control and is as good as it can possibly be after what he called four attempts at causing serious explosions. He said the blasts were almost simultaneous and mentioned only one casualty, stressing that it was not a fatality.
The noontime explosions come exactly two weeks after a series of blasts on subway trains and a city bus killed at least 56 people.
