Bermudians in Britain were urged to be alert of their surroundings after a terror attack in London yesterday.

Police launched a manhunt after an explosion on a District Line train from Wimbledon during the morning rush hour left at least 20 people injured.

The Government of Bermuda London Office stated on social media: “The London Office would like to advise Bermudians in the UK to remain vigilant of their surroundings following the events in London.

“Please be reminded the London Office is here to assist Bermudians in the UK.

“In incidents such as today, we welcome Bermudians to utilise the London Office should they require any assistance in liaising with family or seeking guidance.”

Meanwhile a Government House spokesman said: “We were appalled to hear about the attack in Parsons Green this morning and our thoughts are with those affected.”

The incident — the fifth terror attack in Britain this year — happened at Parsons Green underground station in the west of the capital at about 8.20am.

Metropolitan Police assistant commissioner Mark Rowley said most of the injured suffered “flash burns” from the explosion. Others were reportedly injured in the “stampede” as they tried to escape.

Prime Minister Theresa May condemned the “cowardly” attack, which she said had “intended to cause significant harm”. According to media reports, the area surrounding the station was evacuated after the homemade bomb was detonated on the commuter train and security services were said to have identified a suspect.
