Bangkok , Thailand ( CNN ) -- Thailand 's national election day has morphed into a day of tense uncertainty after chaos prevented voting in several districts . Of the 375 constituencies nationwide , 92 reported voting-related incidents . The Bangkok district of Laksi postponed its election for about 87,000 voters Sunday because protesters were blocking the administrative office where the ballot boxes are kept , national security chief Paradorn Pattanathabutr said . The new voting date has not been set . Laksi , a district of mixed pro- and anti-government sentiment , saw violent protests Saturday when gunfire erupted during anti-government protests , witnesses said . At least eight people have been wounded since Saturday , the Erawan Medical Centre said . And in the Bangkok district of Din Daeng , voting was called off because government protesters blocked officials from distributing ballot boxes . A group of government supporters responded by gathering at the Din Daeng district office chanting , `` Election , election '' and `` We want to vote today . '' They raised their fists and held up their voter registration cards -- but to no avail . At a rally Sunday , an opposition leader urged protesters to remain peaceful and to continue boycott efforts by shutting down government offices Monday . `` We need to keep our principles . We fight in peace , with no weapons and violence . We only fight with our feet and whistles , '' People 's Democratic Reform Committee leader Suthep Thaugsuban said . `` We have the right to a peaceful protest . '' Even before voters started casting their ballots , the opposition Democrat Party appeared to be bracing for a battle . On Friday , an attorney for the party filed a petition asking the nation 's constitutional court to declare Sunday 's election invalid , arguing that some areas could not hold elections and some polling stations would not be able to count votes . The turmoil stems from a monthslong campaign against Prime Minister Yingluck Shinawatra . Since November , at least 10 people have died and nearly 600 have been wounded in violence . Despite the continued chaos , some voters in Bangkok insisted on casting their ballots . `` I 'm very excited to exercise my right to vote today , '' Nopphorn Tabupha said from Bangkok 's Bueng Kum district . `` I did n't think I would be able to come out . I thought I was going to be blocked by the protesters . '' Meanwhile , many opposition activists , including Suriya Phodhikul , have already rejected the vote . `` No , I did n't ( vote ) -- I want reform before elections . Because if I did , we will only get bad people , corrupt politicians , '' Phodhikul said . Shinawatra called this week 's elections in December in a bid to ease mounting tensions on the streets of Bangkok . But the demonstrators and the main opposition party with which they 're affiliated have already rejected the vote . The Prime Minister 's party is expected to win comfortably . Her brother , Thaksin Shinawatra , is a business tycoon who became prime minister before being overthrown in a military coup . He has since lived in exile , but his opponents accuse him of dominating politics from afar , including through his sister .
