The attempted assassination of Argentine Vice President Cristina Fernandez de Kirchner by a Brazilian has forced Brazil's main presidential candidates to re-evaluate their security arrangements ahead of the Oct. 2 vote, sources said on Friday.
Kirchner escaped unharmed on Thursday after a 35-year-old man of Brazilian origin fired a loaded gun, just inches (cm) from her head, that failed to go off. The shooter's nationality underlined growing concerns about political violence in highly polarized Brazil in the lead-up to its election.
