Truckers who support Brazil¡¯s outgoing President Jair Bolsonaro escalated their protests on Monday, blocking roads throughout the country in actions that could affect exports in one of the world¡¯s top food producers and cause wider economic chaos.

Bolsonaro lost Sunday¡¯s election to leftist former President Luiz Inacio Lula da Silva, but has yet to concede defeat. He will not publicly address his defeat until Tuesday, a cabinet minister said on Monday evening, amid doubts over whether the far-right nationalist will accept Lula¡¯s victory.

Video footage showed some truckers at roadblocks calling for a military coup to prevent Lula becoming president, as protests spread from Mato Grosso and Santa Catarina to Parana, Sao Paulo, Minas Gerais, Goias and Bahia.
