A subway train derailed in east London during rush-hour Thursday. One person was injured in the accident, which police said was not related to terrorism.
One passenger suffered a minor leg injury when the Central line train derailed at 9:04 a.m. local time between the Bethnal Green and Mile End stations, British Transport Police said.
Paramedics were attending the scene, but there were no immediate reports of further injuries. The accident was reportedly caused by an obstruction on the tracks, according to Transport of London.
A large section of the underground line was suspended and authorities were taking hundreds of people off the train.
Britain remains on alert following last week's attempted car bombings in London and a fiery vehicle attack in Glasgow. Authorities say the failed bombings bear all the characteristics of an Al Qaeda operation.
In July 2005, suicide bombers struck London's public transport system, killing 52 people.
