'Six people feared dead' following Plymouth shooting incident

As many as six people are feared to have died following a "serious firearms incident" in Plymouth.
Witnesses described hearing gunshots on Thursday evening, with one saying she saw a man "randomly" start shooting at people in the Keyham area of the city.
Emergency services were called to Biddick Drive shortly after 6 pm [1700 GMT] on Thursday.
A source told the PA news agency that as many as six people could have been killed in the incident.

The force said a critical incident had been declared, the area cordoned off, and it believes the situation is "contained."
Local MP Johnny Mercer tweeted that the incident is "not terror related."
One witness, who lives near Biddick Drive and gave her name as Sharron, told the BBC: "Firstly, there was shouting, followed by gunshots - three, possibly four to begin with.
"This was when the shooter kicked in the door of a house and randomly started shooting... he ran from the house shooting as he ran and proceeded to shoot at a few people in the Linear Park up from the drive."
Robert Pinkerton told the BBC he had "walked around the corner" and "bumped into a bloke with a shotgun."
