Brazil is beefing up funding for the military to help it meet security needs for the Olympics that open next month in Rio, the interim government announced.
Sports Minister Leonardo Picciani said that despite a budget crunch, the government is granting the armed forces an additional $US24 million ($A31.4 million) at the request of the Defence Ministry.
"It is the necessary amount for our defence forces to do their work and that money will be available," Picciani told journalists after a meeting at the presidential palace in the capital of Brasilia.
The minister said the additional funds are meant for "final adjustments" in security before the sports extravaganza.
Troops will begin patrolling sports venues from July 24.
