Police fire tear gas, detain hundreds in Brazil

STORY: Lula, who announced a federal security intervention in Brasilia lasting until Jan. 31 after capital security forces were initially overwhelmed by the invaders, blamed Bolsonaro for inflaming his supporters after a campaign of baseless allegations about potential election fraud.

The president's allies also raised questions about how public security forces in the capital Brasilia were so unprepared and easily overwhelmed by rioters who had been planning on social media for days to gather for weekend demonstrations.

By 6:30 p.m. local time (2130 GMT) security forces had managed to retake the capital's most iconic three buildings.
