British Prime Minister David Cameron has paid tribute to Ms Cox, saying Britain has lost an MP with great passion and a huge heart.
"This is absolutely tragic and dreadful news. My thoughts are with Jo's husband Brendan and the two children, and their wider family. We've lost a great star."
Labour leader Jeremy Corbyn said: "We have lost a much loved colleague, a real talent and a dedicated campaigner for social justice and peace. But they [Cox's family] have lost a wife and a mother, and our hearts go out to them.
A 77-year-old man also received minor injuries.
A 52-year-old man has been arrested by police.
Ms Cox, 41, was left bleeding on the footpath after the attack.
She was taken to hospital by air ambulance, but later died.
"Police were called to a report of an incident on Market Street, Birstall, where a woman in her 40s had suffered serious injuries," says a West Yorkshire Police spokesman.
"Armed officers attended and a 52-year-old man was arrested in the area."
Campaigning has been suspended by both sides of the EU referendum debate as a mark of respect.
