The devastating news that British MP Jo Cox has died following the shooting incident earlier today by a mentally unstable man...

U.K. Labour Party lawmaker Jo Cox died after being attacked as she met constituents in her electoral district in West Yorkshire in the north of England.

Campaigning ahead of next week’s referendum on Britain’s membership of the European Union was suspended for the rest of Thursday by both sides after the attack, which happened just before 1 p.m.

Jo was attacked by a man who inflicted serious and, sadly, ultimately fatal injuries,” West Yorkshire Police Temporary Chief Constable Dee Collins said in a televised press conference in Wakefield.

The Press Association reported that Cox was shot twice. Eyewitnesses speaking to the BBC described her attacker as having a homemade gun.

The Guardian newspaper reported an eyewitness saying Cox’s attacker had shouted “Britain First.” That’s the name of a group that campaigns against immigration and Britain’s membership of the EU.
