Supporters of embattled Venezuelan President Nicolas Maduro stormed the opposition-controlled National Assembly on Wednesday, injuring several lawmakers, witnesses said.
The Independence Day clashes are the latest outbreak of violence in a country struggling with a deepening economic crisis and sometimes bloody street protests demanding a change of government.
Video from inside the building showed blood on walls and wounded lawmakers being tended to by colleagues.
At least seven legislative employees and five lawmakers have been injured, according to National Assembly President Julio Borges.
Journalists inside the assembly building said that they had also been assaulted.
