World mourns Cox's death, killer says 'Death to traitors, freedom for Britain' in court

Jo Cox had a prestigious Cambridge University education and went on to work with an international aid organization Oxfam.

She had also served as an adviser to the Bill and Melinda Gates Foundation and to Sarah Brown, the wife of former Labour Prime Minister Gordon Brown.

In the 2015 general election, she was elected as MP for Batley and Spen.

Helena Joanne 'Jo' Cox, a Britain Labour MP from Batley and Spen died after a man in her constituency stabbed and shot her.

Cox was a "Remain in EU" supporter.

Cox was airlifted to Leeds General Infirmary after the fatal attack in the market town of Birstall around 1pm GMT.

A 77-year-old man was also attacked but he survived and only sustained injuries.

The man responsible for Jo Cox's death had been captured by the local police.

At least three named witnesses claimed that the attacker was a white male, wearing a baseball cap who had screamed "Britain first" during the attack.

Other eye witnesses claimed that the MP was targeted after she got involved in an altercation between two arguing men.

The campaigns of all the "Vote Leave" and "Remain" groups for the June 23 referendum on Britain's destiny in the European Union were suspended for the day after the attack.

MPs and others parliamentarians said they were horrified and paid their tributes to Cox.

Cox's husband Brendan Cox too in a statement asked the people to fight against the hate that killed his wife.

While the death of MP Jo Cox shocked the world, her killer Thomas Mair when presented in court said "Death to traitors, freedom for Britain".

President Obama called Cox's husband to express his grief; David Cameron and Labour leader Jeremy Corbyn brought bouquets at the scene of her death.

A fund created in Cox's memory raised over £250,000 ($359,000) and will go towads charities.
