CNN : It’s been a month since violent clashes between opposition demonstrators and government forces in Venezuela first grabbed global attention. Protests rage on, and demonstrators show no sign of backing down. Medical sources at a hospital in Venezuela’s Carabobo state said a student protester and a 42-year-old man were killed in clashes there Wednesday. State media accused violent right-wing groups of attacking a worker’s march there. In a Twitter post, state Gov. Francisco Ameliach said a national guard captain had been killed in fighting, which he described as “terrorism.” A government tally released Tuesday said at least 23 people had been killed nationwide and more than 200 others have been injured since protests started. The tally did not specify whether the casualties occurred among demonstrators or government forces, or both. Student protesters on both sides packed streets in Caracas Wednesday. State-run VTV showed pro-government demonstrators waving flags with the face of former President Hugo Chavez as they marched. Opposition student protesters also marched in the country’s capital, CNN affiliate Globovision reported, calling for the resignation of the government’s ombudsman. Violence surged this week in Tachira state, which borders Colombia. Government forces shot tear gas at opposition barricades there, and a well-known student leader was gunned down Monday.
