A shooting in Plymouth has claimed the lives of six individuals, including a suspected gunman.
Three ladies, two males, and the suspect killed in the Keyham district of the city on Thursday evening, according to Devon and Cornwall Police.
According to an MP, one of the victims was a child under the age of ten, but the shooting was not terror-related, police said.
Because of the high death toll, it is the worst mass shooting in the United Kingdom in more than a decade.
On Thursday, soon after 18:00 BST, emergency services were dispatched to Biddick Drive.
As the emergency response unfolded, residents were advised to remain indoors and heed police advice.
Sharron, a neighboring resident who did not want to disclose her full name, described the incident as "horrific and incredibly terrible."
"There was shouting first, followed by gunfire - three or four at first," she recalled.
"When the shooter burst in the door of a residence and began firing at random, this was the scene. He bolted from the home, shooting as he went, and then opened fire on a couple individuals in the linear park adjacent to the drive."
Two females and three males died at the scene, according to Devon and Cornwall Police, while one female died shortly after in hospital.
"The area has been blocked off, and police are not looking for anyone else in relation to the incident," the statement continued.
Luke Pollard, MP for Plymouth Sutton & Devonport, described the tragedy as "unspeakably horrific" and said he was "utterly heartbroken" to find that one of the victims was a child.
Priti Patel, the Home Secretary, tweeted: "The event in Plymouth is shocking, and my heart goes out to all who have been touched. "I spoke with the chief constable and expressed my whole support.”
"I ask everyone to remain calm, heed police instructions, and let our emergency services do their work."
The last mass shooting in the United Kingdom occurred in Cumbria in 2010, when taxi driver Derrick Bird killed 12 people.
