LONDON, England (CNN) -- Emergency services personnel are attending three different Tube stations in central London following reports of "incidents," police say.
Scotland Yard told CNN Thursday one incident was also reported on a bus in Hackney, in east London. No casualties have yet been reported.
Meanwhile a nail bomb exploded at London's Warren Street underground station, a source at a city transport company told Reuters news agency. One passenger on an Underground train told Sky TV a traveler's rucksack had exploded on the Tube outside the station.
The reports came two weeks to the day since bombs on three Underground trains in London and a double-decker bus killed 56 people including four bombers. A Scotland Yard spokesperson told CNN that Warren Street, Shepherds Bush and Oval stations had all been evacuated.
There are no reports of any casualties at this stage, sources told the UK Press Association. London Underground confirmed that services on three lines -- Victoria, Northern and Hammermith and City -- were suspended following the incidents, according to PA.
No further information is yet available. Passengers at Warren Street reported seeing smoke but police could not confirm this.
Ivan McCracken told Sky News: "I was in a middle carriage and the train was not far short of Warren Street station when suddenly the door between my carriage and the next one burst open and dozens of people started rushing through. Some were falling, there was mass panic.
"It was difficult to get the story from any of them what had happened but when I got to ground level there was an Italian young man comforting an Italian girl who told me he had seen what had happened.
"He said a man was carrying a rucksack and the rucksack suddenly exploded. It was a minor explosion but enough to blow open the rucksack.
"The man then made an exclamation as if something had gone wrong. At that point everyone rushed from the carriage." The reports came two weeks to the day since bombs on three Underground trains in London and a double-decker bus killed 56 people including four bombers.
