The United States government has imposed sanctions on the head of Sudan’s Transitional Sovereign Council Gen. Abdel Fattah al-Burhan in a statement on Thursday.

Washington accuses al-Burhan of prioritizing war over negotiations to bring an end to the conflict that has killed tens of thousands of people and driven millions from their homes.

“Today’s action underscores our commitment to seeing an end to this conflict,” said Deputy Secretary of the Treasury Wally Adeyemo.

“The United States will continue to use our tools to disrupt the flow of weapons into Sudan and hold these leaders responsible for their blatant disregard of civilian lives.”

The U.S. Treasury Department also said the war tactics of the army led by the junta leader have included indiscriminate bombing of civilian infrastructure, attacks on schools, markets and hospitals, and extrajudicial executions.

Washington announced the measures, first reported by Reuters, just a week after imposing sanctions on Burhan’s rival in the two-year-old civil war, Mohamed Hamdan Dagalo, commander of the paramilitary Rapid Support Forces.

Speaking earlier on Thursday in an interview with Al Jazeera, Burhan was defiant about the prospect that he might be targeted.

His arch enemy Gen. Mohamed Hamdan Dagalo has also been sanctioned by the US government.
