In a highly unusual intervention, Secretary of State Rex Tillerson plans to remove Iraq and Myanmar from a U.S. list of the world's worst offenders in the use of child soldiers, disregarding the recommendations of State Department experts and senior U.S. diplomats, U.S. officials said.

The decision, confirmed by three U.S. officials, would break with long-standing protocol at the State Department over how to identify offending countries and could prompt accusations the Trump administration is prioritizing security and diplomatic interests ahead of human rights.

Tillerson overruled his own staff's assessments on the use of child soldiers in both countries and rejected the recommendation of senior diplomats in Asia and the Middle East who wanted to keep Iraq and Myanmar on the list, said the officials, who have knowledge of the internal deliberations.
