"I look forward to welcoming Ambassador David Satterfield in the coming days as the US Special Envoy for the Horn of Africa once Ambassador Jeffrey Feltman ends his appointment," Blinken said in a statement via Twitter.

Blinken noted that the Biden administration invited Feltman to this position in early 2021 but intended his appointment to last less than a year.

"However, the ongoing instability in the Horn of Africa and the region's interlinked political, security and humanitarian challenges demand sustained focus by the United States," he said.

Blinken also said he is confident Satterfield will help to promote a peaceful and prosperous Horn of Africa.

Feltman will continue working at the State Department in an advisory capacity, Blinken added.
