Tensions have risen in Venezuela since Lopez, a 42-year-old Harvard-educated economist, turned himself in to troops on Tuesday after spearheading three weeks of often rowdy protests against President Nicolas Maduro's government.

The latest included college student and model Genesis Carmona, 22, who was shot in the head at a protest on Tuesday in the central city of Valencia. She died later in a clinic.

There was sporadic trouble across Venezuela again on Wednesday. Rival groups scuffled outside the Caracas court where Lopez was due, while student demonstrators also blocked a highway in the capital, burning trash.
