Colombia's public prosecutor is calling for an investigation into whether former President Alvaro Uribe was linked to a massacre carried out by paramilitaries in 1997.
The prosecutor's office confirmed Tuesday that it had asked the Supreme Court to look into whether Uribe was connected to the attack, which left 15 people dead in El Aro, in Antioquia state, near Medellin.
Uribe was president until 2010 and is now a senator who helps lead the South American country's right wing. He was governor of Antioquia the time of the massacre.
A local court this year made a similar request for a probe, citing the presence of a government helicopter at the scene of the killing.
Uribe referred to the latest moves against him as slander.
