Venezuelan opposition candidate Edmundo Gonzalez Urrutia has ignored a second summons to appear before prosecutors investigating his claim to have won the July 28 presidential election. The opposition claims Gonzalez Urrutia won by a landslide, while the government insists President Nicolas Maduro won. The situation has escalated tensions in Venezuela, with both sides calling for protests. International pressure is mounting on Maduro to release detailed election results, but the outcome remains uncertain.
