In Pictures: Brazil in chaos as protesters storm government buildings

Brazilian security forces locked down the area around Congress, the presidential palace and the Supreme Court Monday, a day after supporters of ex-president Jair Bolsonaro stormed the seat of power in riots that triggered an international outcry.

In stunning scenes reminiscent of the January 6, 2021 invasion of the US Capitol building by supporters of then-president Donald Trump, backers of Bolsonaro broke through police cordons and overran the seats of power in Brasilia, smashing windows and doors and ransacking offices.

Rioters ransacked congress, the presidential palace and the top court in Brasilia on Sunday hoping to trigger a military intervention. It took hours for security forces to regain control of the main government buildings. Hundreds of arrests were carried out through the night, but thousands of Bolsonaro supporters remained in the area.

Lula, who was visiting a city destroyed by rains in the state of Sao Paulo, returned late to capital to take stock of the situation. He decreed federal intervention in the security of the federal district, which will likely be confirmed by congress during an extraordinary session early on Monday. In a show of strength, he's likely to meet with the heads of congress and the top court, as well as state governors who are expected to fly into Brasilia.
