A British politician is dead after being shot and stabbed following a meeting with constituents, The Guardian reported Thursday.

Jo Cox, a Labour Party member of Parliament, was attacked in her West Yorkshire constituency.

West Yorkshire Police Chief Constable Dee Collins said at a press conference hours after the attack that Cox had died.

Another man also suffered slight injuries, police said.

Police arrested a man in the area after the attack who reportedly shouted "Britain First," according to the Daily Mirror.

Police are not looking for anyone else in connection with the deadly assault, the BBC reported.

The incident has drawn comparisons in the U.S. to the January 2011 shooting of former Rep. Gabby Giffords (D-Ariz.).

A man shot Giffords in the head as she spoke to constituents in Tucson, Ariz., forcing her to retire from Congress. Six people were killed and 13 injured in that mass shooting.

In Britain, tensions are high a week before the nation will vote on whether to leave the European Union.

Labour leader Jeremy Corbyn issued a statement after Cox died, saying the Labour family and the entire country is "in shock and grief at the horrific murder." 

He praised Cox, saying she had a "lifelong record of public service and a deep commitment to humanity."

"Jo Cox died doing her public duty at the heart of our democracy, listening to and representing the people she was elected to serve," Corbyn said in a statement posted to Twitter.

"It is a profoundly important cause for us all."

Corbyn offered his condolences to Cox's family, and called her a "much loved colleague, a real talent and a dedicated campaigner for social justice and peace."

British Prime Minister David Cameron also expressed his condolences.

“The death of Jo Cox is a tragedy,” Cameron wrote on Twitter. 

“She was a committed and caring MP. My thoughts are with her husband Brendan and her two young children."

Democratic National Committee Chairwoman Debbie Wasserman Schultz tweeted her condolences as well:

Cox was elected to Parliament in 2015 and chairs the all-party parliamentary group for Friends of Syria.
