Several people have been killed in a mass shooting in the city of Plymouth in south-west England, in an incident described by the British home secretary as “shocking”.
The Times newspaper reported that up to six people were killed in the shooting and The Daily Telegraph said a gunman was reportedly shot dead.
It was unclear if he had killed himself or was shot by police.
Police did not confirm the number of fatalities in what they described as a “serious firearms incident”, but said the situation was believed to be contained.
Britain has one of the lowest gun homicide rates in the world, and mass shootings are rare.
Sharron Turner, 57, who lives behind the scene of the shooting, told The Times that a gunman had “kicked in” the front door of a semi-detached house before shooting a young mother and her daughter, who was aged about five.
Ms Turner said she had been told the man, who was dressed in black and grey, was armed with a semi-automatic weapon.
After the attack the gunman escaped through a park behind the house and shot two dog walkers, The Times reported.
Local MP Johnny Mercer said on Twitter that the incident was “not terror related”.
“The incident in Plymouth is shocking and my thoughts are with those affected,” Home Secretary Priti Patel said on Twitter.
The South Western Ambulance Service earlier said it had responded to an incident with a significant number of resources, including Hazardous Area Response Teams, multiple ambulances, air ambulances, multiple doctors and senior paramedics.
