Watch: England mass shooting kills 6, including suspect
The shooting in Plymouth on Thursday evening, which left six people dead including a child, has sparked shock and distress across the UK.
Gunman Jake Davison, 22, killed five people including a three-year-old girl in a six-minute shooting spree before turning the weapon on himself, police have confirmed.
The other victims were aged between 43 and 66.
A 53-year-old woman and a 33-year-old man are being treated in hospital after being shot at by Davison.
Mass shootings are a rarity in the United Kingdom, with the last taking place more than a decade ago when Derrick Bird killed 12 people in Cumbria.
These are some of the previous shootings that have taken place in the UK, of which some sparked changes to the laws around firearms:
The Hungerford Massacre - 19 August, 1987
On 19 August, 1987, unemployed labourer Michael Ryan embarked on a six-hour shooting spree in the Berkshire town of Hungerford, using a semi-automatic rifle, an M1 Carbine and a Beretta pistol.
He killed 16 people including his own mother and police officer Roger Brereton – who was later posthumously awarded the Queen's Commendation for Brave Conduct – injuring 15 more and then turning the gun on himself.
The massacre prompted the passing of the Firearms (Amendment) Act 1988 following a report commissioned by then-Home Secretary Douglas Hurd.
The act banned semi-automatic and pump-action rifles; weapons that fire explosive ammunition; short shotguns with magazines; and elevated pump-action and self-loading rifles. It also required shotguns to be registered and kept in secure storage.
The Monkseaton Shootings - 30 April, 1989
On 30 April, 1989, 22-year-old Robert Sartin began shooting indiscriminately at people in Monkseaton, Tyne & Wear with his father's double-barrelled shotgun.
The 20-minute spree left one man dead and 14 injured before Sartin was arrested.
Sartin was charged with the murder of Kenneth Mackintosh in Windsor Road, Monkseaton, and 17 counts of attempted murder. He pleaded not guilty by reason of insanity at Durham Crown Court in May 1996 and was subsequently detained indefinitely at a secure mental unit.
The Dunblane Massacre - 13 March, 1996
The deadliest mass shooting in British history, the Dunblane Massacre took place at Dunblane Primary School near Stirling, Scotland.
On that day, Thomas Hamilton shot dead 16 pupils and one teacher, injuring 15 others before killing himself.
The tragedy led to the introduction of two new Firearms Acts which banned the private ownership of most handguns within the United Kingdom.
The Cumbria Shootings - 2 June, 2010
On 2 June, 2010, taxi driver Derrick Bird embarked on a shooting spree in Cumbria, killing 12 people and injuring 11 others before committing suicide.
The shootings started in Lamplugh, moving to Frizington, Whitehaven, Egremont, Gosforth, and Seascale, sparking a major manhunt. Bird was eventually found dead in a wooded area after abandoning his car in the village of Boot.
Raoul Moat - July 2010
Raoul Moat sparked a major manhunt after shooting his ex-girlfriend, her new partner and police officer David Rathband with a sawn-off shotgun two days after being released from prison.
Moat, 37, went on the run for nearly a week following the shooting, before killing himself near Rothbury, Northumberland, after a six-hour standoff with armed police officers.
Chris Brown, Moat's ex-girlfriend Samantha Stobbart's new partner, was killed in Moat's originally shooting spree, while she was hospitalised. Pc Rathband was permanently blinded.
