Supporters of the far-right president have erected hundreds of roadblocks across Brazil since it was announced that Mr Bolsonaro's left-wing rival Lula won the election.Angry with the result, lorry drivers set up blockades across the country.Police have struggled to contain all of the blockades, although the federal highway police said more than 700 had now been dismantled.Addressing the blockades in a video posted on his Twitter account on Wednesday, Mr Bolsonaro said: "I know you are upset... Me too.However, he encouraged protesters to find other means of demonstrating and welcomed the various rallies that have been held in his support, in which people have displayed Brazilian flags and chanted anti-Lula slogans."
