Caracas - Deadly violence erupted around a controversial vote in Venezuela on Sunday, with a candidate in the election and a youth opposition leader gunned down, and troops and protesters attacking each other in Caracas and elsewhere."I don't know where their hate comes from.... This is war!" one resident, Conchita Ramirez, told the Vivo Play television network as she described troops firing at buildings and people in the capital.At least five people died overnight and into Sunday, prosecutors said, swelling a toll from four months of anti-government protests that was already over 110 killed.The fiery unrest confirmed fears over the vote for a new "Constituent Assembly" called by beleaguered President Nicolas Maduro in defiance of months of demonstrations and fierce international criticism.He is gambling his four-year rule on the 545-member citizens' body that will be empowered to dissolve the opposition-controlled congress and change laws as it reforms the nation's constitution.A 39-year-old lawyer who was a candidate in Venezuela's southeastern town of Ciudad Bolivar was killed from multiple shots fired by assailants who broke into his home overnight, prosecutors said, adding the motive was as yet unknown.In a protest in the northeast town of Cumana, a 30-year-old regional secretary for a youth opposition party was shot dead in an anti-election protest.The bodies of two men shot dead, aged 28 and 39, were found after a protest Sunday in the western state of Merida, where a 38-year-old man was killed on Saturday in another demonstration.In eastern Caracas, four soldiers were wounded when an improvised explosive targeted their motorbike convoy. In the west of the city, national guard troops fanned out, using armoured vehicles, rubber bullets and teargas to disperse protesters blocking roads.Soldiers also violently moved against protesters in the second city of Maracaibo, in the west, and Puerto Ordaz in the east.The opposition had called for a boycott and mass demonstrations against the election, which it called a bid by Maduro to install a dictatorship with the backing of the military.Maduro is 'first voter' Maduro kicked off voting by casting his ballot in a west Caracas polling station."I'm the first voter in the country. I ask God for his blessings so the people can freely exercise their democratic right to vote," the president said. He was accompanied by his wife, Cilia Flores, who is a candidate to sit on the new assembly.Turnout will be key to determining the legitimacy of the election. But that will be difficult to ascertain as most voters will be able to vote twice, because candidates were drawn from social and industry sectors as well as geographically. Surveys by Datanalisis, a pro-opposition polling firm, show more than 70% of Venezuelans opposed the idea of the new assembly - and 80% reject Maduro's leadership.Maduro decreed a ban on protests during and after the vote, threatening prison terms of up to 10 years for anyone violating the order.Fear of the violence worsening has rippled across the region, and beyond. The US, the EU and Latin American powers, including Argentina, Brazil, Colombia and Mexico, have come out against the election, saying it would destroy Venezuelan democracy.Several foreign airlines, including Air France, Delta, Avianca and Iberia have suspended flights to the country over worries about security.The US has ordered the families of its diplomats to leave after imposing sanctions on 13 current and former Venezuelan officials.Maduro has described the election as the most important Venezuela has seen, and the Constituent Assembly a "card that will win this game."One voter on Sunday, Ana Contreras, said: "I have come to vote to tell the gringos and the opposition that we want peace, not war, and that we support Maduro."An opposition leader, Henrique Capriles, said "the government wants to sell the Constituent Assembly as a solution to the problems. But it's only aggravating them."The head of Datanalisis, Luis Vicente Leon, said the Constituent Assembly was being formed because the uncharismatic Maduro - whose term is meant to finish next year - "can't win elections."Regional rejection Colombia and Panama - refuges for tens of thousands of Venezuelans fleeing the chaos at home - have said they will not recognize the results of Sunday's election in Venezuela.The US has suggested further sanctions could follow. The oil industry is worried they could target Venezuela's crude exports, 40 percent of which are bought by the United States.Some in Maduro's administration have broken ranks with him, most prominently his attorney general. Two diplomats resigned this week in dissent: one at the United Nations and another at the embassy in Panama.The Venezuelan leader has blamed the mounting unrest against him and his policies on the United States, working hand-in-hand with the Venezuelan opposition to wage an "economic war."
