There has been feverish campaigning ahead of the June 23 referendum on whether or not Britain should leave the European Union.

Prime Minister David Cameron had been expected to speak on behalf of the "remain" camp on Gibraltar. His Downing Street office did not have details on his plans.

Britain's Press Association reports Labour lawmaker Jo Cox has been injured in a shooting near Leeds.

The PA was quoting eyewitness Hithem Ben Abdallah as saying Cox got involved in a scuffle between two men in the village of Birstall on Thursday. Abdallah said one of the men was fighting with Cox and then a gun went off twice and "she fell between two cars and I came and saw her bleeding on the floor."

After around 15 minutes, the shop owner said emergency services arrived and tended to her with a drip.

Police say a "serious incident" has taken place, but didn't immediately identify the victim or provide any more details.

Cox's assistant confirmed to the PA she had been attacked.
