At least two people were killed and more than 20 injured Friday when Venezuelan troops battled with opposition protesters who demanded that President Hugo Chavez submit to a recall vote, emergency services officials said.
Gunfire broke out during several hours of clashes that turned parts of Caracas into a war zone and delayed the start of an international summit on poverty.
Hundreds of national guard troops backed by armored vehicles fired volley after volley of tear gas and rubber-coated bullets to drive back thousands of protesters.
