New clashes have taken place in Brazil despite President Dilma Rousseff's attempt to respond to protesters' demands and halt the violence, BBC reported.
Trouble was reported in Belo Horizonte and Salvador, the two cities hosting Confederations Cup matches on Saturday.
Largely peaceful protests continued in dozens of Brazilian cities on Saturday, including Sao Paulo.
President Rousseff announced several reforms on Friday as she tried to bring an end to days of demonstrations.
The demonstrations began over transport fare rises in Sao Paulo, but quickly grew into nationwide rallies encompassing a raft of issues, from corruption and the poor quality of public services to the cost of hosting the current Confederations Cup and next year's Fifa World Cup.
