Videos on social media showed travellers rolling their suitcases at night along the highway to the Sao Paulo’s international airport after the highway to and from the facility was blocked by Brazilian truckers on Tuesday.

Dozens of flights were delayed by the protest by supporters of President Jair Bolsonaro after his election loss to former President Luiz Inácio Lula da Silva.

Truck drivers have jammed traffic in areas across the country and said they won’t acknowledge Bolsonaro’s defeat. (At press time Bolsonaro had not conceded defeat).

By noon Tuesday, highway police said they had removed 306 blockades, but more than 260 were still in place, according to the Ministry of Justice Access and access to the airport was partially re-established.

A majority of Brazilian Supreme Court justices early Tuesday had voted to order the federal highway police to clear the blocked roads immediately and Federal public prosecutors in Sao Paulo and Goias states said they had opened investigations into the blockades.

In neighbouring Minas Gerais, a key battleground state in the election, a video on social media showed a protester telling a reporter “We won’t stop as long as we don’t have a response from our president.”

The man, wearing a green-and-yellow shirt – the colours of the Brazilian flag and of the nation’s conservative movement – claimed the election was “fraudulent” and warned of future protests.

“We want Bolsonaro in 2023 and for the years to come,” he said.
