Johan Van Hecke, the head of the European Union's election observer mission, speaks to the journalists as the pools close on the day of the presidential election in Bissau on June 28, 2009. Voters in Guinea-Bissau went to the polls on June 28 to elect a new president after a series of assassinations, including that of long-time leader Joao Bernardo Vieira, who was killed by members of the army on March 2 in apparent revenge for a bomb attack that claimed the life of the army chief, General Batista Tagme Na Waie.
