In total, 170,000 people are expected to be deployed¹ to guarantee security across the 12 host cities.

 

On Wednesday, President Dilma Rousseff said the armed forces could also be brought in if needed. 

 

Since last June, protesters have staged a number of street marches, with some violent episodes, raising concerns about security at the tournament. 

 

Earlier this month, a cameraman died after being hit by fireworks apparently² launched by protesters.

 

In January, the organisers had suggested the tournament's security personnel would total 100,000 people.

 

 

But at a security workshop on Thursday, the organising committee said this figure should be increased. 

 

"We have a lot of concerns, not so much about protests which are a democratic right, but rather about potential violence. We are committed to preventing violence during any protest activity," a Justice ministry³ official, Andrei Rodrigues, told reporters.

 

Around 150,000 personnel will be from the armed services and police.

 

But an extra 20,000 security stewards⁴ will be trained to work inside the 12 stadiums of the tournament, organisers say.

 

Also on Thursday, Brazil launched its first naval⁵ preparatory exercise ahead of the World Cup.
