Brazil's military will reinforce police providing security at hotels and training camps for the teams playing in the FIFA World Cup, the defence ministry said today. So far security at protests has been the responsibility of state police. A defence spokesman said President Dilma Rousseff's office had authorized the decision on Monday. Brazil will play the opening match of the tournament against Croatia on June 12.The Army will also be charged with anti-terrorism operations, border security and protecting strategic infrastructure during the tournament, including ports, airports, power stations and water supplies. The protesters are angry over the more than 11 billion dollars being spent on the tournament, saying the government should prioritize health, education and transport instead. Brazil has mobilized 57,000 troops to provide security during the World Cup.
