President Iván Duque of Colombia, under fire over concerns that his military may be committing human rights abuses in its pursuit of armed groups, said Friday that he was appointing an independent commission to review orders and operational instructions issued by the army.

The initiative came less than a week after The New York Times disclosed army orders from this year instructing top commanders to “double the results” of their military missions against guerrilla, paramilitary and criminal organizations in Colombia.

The orders have caused unrest among some senior army officers, who said the new pressure to carry out attacks had heightened the risk of civilian casualties and had already led to suspicious deaths by overzealous soldiers.

Mr. Duque said he would create the commission, to be composed of prominent Colombian jurists, to perform a “rigorous analysis of all orders, manuals and operational documents.” He said the goal would be to ensure that the military’s orders conform to human rights law.
