Asunción, March 15 (RHC)-- In Paraguay, lawmakers have requested a political trial against President Horacio Cartes, just a month before the presidential elections, scheduled for April 22.

The lawmakers evoked the upcoming one-year anniversary of the police killing of opposition leader Rodrigo Quintana on March 31.

The requested political trial against Cartes, they said, would be as a protest against "state terrorism."

Opposition leader Rodrigo Quintana was killed in violent clashes sparked by a secret Senate vote on a constitutional amendment that allowed President Cartes to run for re-election.

Quintana, 25, was killed by a rubber bullet fired by police who entered the headquarters of the Liberal Party, the country's second-largest political party.

The request followed another political trial, this one launched by opposition Colorado representatives and targeting Paraguay's General Treasury Inspector Enrique Garcia over corruption charges.

Cartes is also being questioned for his candidacy for a seat in Senate, with several leftist opposition parties appealing the decision by Asuncion's electoral court to allow him to run, including the Frente Guasu coalition, the Progressive Democratic Party and the Revolutionary Febrerista Party.

According to Frente Guasu, Cartes' candidacy is also not compatible with the National Constitution, articles 189 and 237,
