John Kirby, the US National Security Council's strategic communications coordinator, said President Joe Biden responded "quickly and boldly" to the targeting of military facilities in Syria, and that US forces would continue their mission in the region, he said.

This came during his participation in a television program on Sunday evening, commenting on the death of a contractor and the injury of 5 US service members, as a result of a drone attack on a facility at a base of the international coalition in northeastern Syria.

"This was a serious attack by a militia, and the president led a bold and swift response to deal with it," Kirby said.

He stressed that US soldiers will remain at the helm of their duties in Syria, stressing that Biden is "very determined to keep soldiers in Syria."

Kirby said additional responses to attacks targeting U.S. personnel and facilities in Iraq and Syria could be implemented "if President Biden deems it necessary."

Local sources told Anadolu Agency on Saturday that the Omar oil fields and Coneco gas and their surroundings were subjected to missile attacks as US forces are stationed in the eastern Syrian province of Deir Ezzor.

On Friday, US Secretary of Defense Lloyd Austin announced that "a drone targeted a facility at an international coalition base in northeastern Syria on Thursday, killing an American contractor and wounding 5 American service members."
