CARACAS (Reuters) - Security forces and protesters fought around Venezuela on Thursday in streets blocked by burning barricades and a supporter of socialist President Nicolas Maduro was shot dead, the sixth fatality from more than a week of violence.

Maduro said a "fascist bullet" killed Alexis Martinez, a brother of a ruling Socialist Party legislator, in the central city of Barquisimeto. A local journalist said Martinez was shot in the chest while passing an opposition protest.
