CARACAS, Venezuela (AP) -- Supporters of Venezuelan presidential candidate Henrique Capriles had just set out for an afternoon of campaigning in a caravan of cars when they came to a road blocked by a crowd of supporters of President Hugo Chavez.
Witnesses said some of those in the caravan had gotten out to try to convince the Chavez supporters to let them through when gunfire rang out. Two Capriles supporters were killed in the violence on Saturday in western Barinas state.
Justice Minister Tareck El Aissami said on Sunday that one suspect has been arrested in the killings.
Opposition politician Pedro Castillo, who witnessed the violence, said there was no physical confrontation before the shooting erupted. He and other opposition politicians called for a thorough investigation to bring those responsible to justice.
