Woman killed by gunfire at Venezuela polling site

A woman has been killed by gunfire that erupted after government supporters on motorcycles swarmed an opposition polling site in Venezuela's capital, Caracas.

Venezuelan's opposition said more than 7.1 million people responded to its call to vote on Sunday in a symbolic rejection of President Nicolas Maduro's plan to rewrite the constitution, a proposal that has raised tensions in a nation suffering through widespread shortages and months of anti-government protests.
