An explosion took place inside a carriage of London’s iconic tube train on Friday morning leaving several passengers injured, officials said. The London Police said that there was a possibility that the blast was carried out by terrorists.

According to officials, the explosion occurred during the morning rush hour at around 8.15 am (local time) at the Parsons Green station in West London and led to a stampede.

A picture that has gone viral on social media showed a white container inside a supermarket bag with red wires, but did not appear to suggest extensive damage in the carriage.

As per initial reports, many passengers have been left with facial burns due to the explosion while the train services between Earl’s Court and Wimbledon have been suspended.

Meanwhile, the British Transport Police (BTP) confirmed the news and said that officers were at the scene.
