THREE MEN HAVE been arrested under the UK’s Terrorism Act after a car explosion at a hospital killed one person and injured another in Liverpool. 

Merseyside Police were called to reports of a blast involving a vehicle – believed to be a taxi – at Liverpool Women’s Hospital at 10.59am on Sunday.

Counter Terrorism Police North West said three men – aged 29, 26, and 21 – were detained in the Kensington area of the city and arrested under the Terrorism Act in connection with the incident.

The male passenger of the car was declared dead at the scene and is yet to be formally identified.

The driver, also a man, was injured at the scene and remains in hospital in a stable condition.

Counter-terrorism police said they continue to keep an open mind about the cause of the explosion and are working closely with Merseyside Police.

Earlier, a spokesman for Merseyside Police said: “So far we understand that the car involved was a taxi which pulled up at the hospital shortly before the explosion occurred.

“Work is still going on to establish what has happened and could take some time before we are in a position to confirm anything.

“We are keeping an open mind as to what caused the explosion, but given how it has happened – out of caution – counter terrorism police are leading the investigation supported by Merseyside Police.

“Our response is ongoing at the hospital and will be for some time. Cordons are in place, and there are some road closures.”

Police said a major incident had been declared.

Images of a vehicle on fire, and later burnt out, at the scene earlier were shared online.

Footage of a number of explosions and billowing smoke outside the hospital were also shared as a bomb disposal unit attended.
