QUITO, June 26 (Xinhua) -- The Ecuadorian-born top leader of the Colombian criminal organization "Border Commandos" has been captured in the United Arab Emirates (UAE), Ecuador's Interior Minister John Reimberg announced Thursday.

The International Criminal Police Organization (Interpol) arrested Roberto Carlos Alvarez Vera in Abu Dhabi, Reimberg said at a press conference.

Alvarez Vera was arrested "for extradition purposes," said the minister, adding the suspect is responsible for the regrettable attack against the Armed Forces of Ecuador in May.

"We will not rest until everyone pays their due to justice," the minister said, noting "the detainee has an Interpol Red Notice, as well as terrorist alerts."

Ecuador blames the "Border Commandos", a dissident group of the defunct Revolutionary Armed Forces of Colombia guerrilla group, for killing 11 Ecuadorian soldiers in an ambush in the Amazonian province of Orellana on May 9.

On June 4, the army reported that a military patrol, made up of two combat teams, had an encounter with armed individuals, possibly dissidents of the Colombian guerrilla group.

Following the incidents, the armed forces ordered the deployment of air units to stop irregular armed groups from neighboring Colombia from crossing the border. ■
