Football's world governing body FIFA has stepped up World Cup security following two fan invasions at Rio's Maracana Stadium.

In a statement released on Saturday, FIFA said reinforcements would be made at each of the 12 World Cup stadiums.

The decision follows a meeting of FIFA officials and local authorities on Friday.

"[We have] decided to reinforce security at the stadia perimeters, both physically and with personnel, and to increase the presence of public security on access control points as well as private security," FIFA said in the statement.

The most serious breach came when dozens of fans stormed the venue's media area before the Group B match between Spain and Chile on June 18.

Security barriers were also breached during Argentina's Group F clash with Bosnia-Herzegovina on June 15.

The Maracana will stage the World Cup final on July 13.
