The top US official in the fight against the Islamic State group has quit over President Trump’s decision to pull troops from Syria, reports say.
Brett McGurk had planned to leave his role next year but brought his departure forward, CBS and AP reported.
Before Mr Trump’s announcement he had insisted that the US would continue working against IS in Syria.
“We want to stay on the ground and make sure that stability can be maintained in these areas,” he had said.
It follows the abrupt resignation of Defence Secretary Jim Mattis, who had opposed withdrawing troops from Syria and reducing the US presence in Afghanistan.
Gen Mattis said the president had the right to appoint someone “whose views are better aligned with yours”.
