Argentines are heading to the polls Sunday for legislative elections, with half the seats in the Chamber of Deputies and one-third of the seats in the Senate up for grabs.

The polls opened at 8:00 a.m. and are scheduled to close at 6:00 p.m.

Some 30.57 million people are eligible to vote for the candidates for 127 Chamber of Deputies seats and 24 Senate seats at play in the midterm election.

Several areas, including the city of Buenos Aires and Buenos Aires, Jujuy, Formosa, Chaco, Catamarca, Santiago del Estero, La Rioja, Mendoza and San Luis provinces, are also holding legislative elections.

About 92,000 police officers and armed forces personnel have been deployed across the country to provide security during the elections, the Defense Ministry said.

President Cristina Fernandez, who is recovering from brain surgery at her official residence on the outskirts of Buenos Aires, will not be able to cast her ballot in the midterm election because she is registered to vote in the southern city of Rio Gallegos.

Sunday also marks the third anniversary of the death of Nestor Kirchner, Fernandez's husband and predecessor in the presidency.

Kirchner died from a heart attack on Oct. 27, 2010, at his residence in El Calafate, a resort city in the southern province of Santa Cruz. EFE
