Bogota, Colombia ? The last major paramilitary leader to enter into a peace deal with the government handed in his weapon Tuesday.

Freddy Rendon Herrera and 745 fighters from the Elmer Cardenas bloc handed in 447 rifles in a disarmament ceremony in Unguia, a village 370 miles northwest of Bogota.

The government said Herrera was the last paramilitary leader to disarm under a 2003 peace deal that promised fighters reduced sentences and protection from extradition to the United States in exchange for their pledge to renounce violence.

Herrera’s group controlled an area of river-laced jungle near the Panama border known as a major corridor for drug and arms traffickers. Before the arrival of the far-right militia, the area was dominated by leftist rebels.
