Argentine authorities have been tightening security in the seaside resort for the 20th Ibero-American summit to be hosted here on Saturday.
About 5,000 security agents including anti-riot and elite troops, have been deployed in the city, as well as logistical troops from the Armed Forces, to ensure the security during the two-day summit.
The authorities have established an “area of exclusion” or “area of extreme security” around the hotel where the summit will take place.
In order to enter the security area, each resident or worker must place their fingerprint on a digital reader so that police can identify them before gaining access to the area.
Leaders from Latin America, Spain and Portugal who are expected to attend the summit include King Juan Carlos of Spain and his wife Queen Sofia as well as Argentine President Cristina Fernandez, Brazilian President Luiz Inacio Lula da Silva and Peruvian President Alan Garcia.
Chilean President Sebastian Pinera, Colombian President Juan Manuel Santos, Costa Rican President Laura Chinchilla and Uruguayan President Jose Mujica will also attend the summit.
Presidents from Bolivia, Evo Morales, and Honduras, Porfirio Lobo, will not attend the meeting, nor will Spanish Prime Minister Jose Luis Rodriguez Zapatero.
