RIYADH: Saudi Arabia and the US have expressed grave concern over the serious violations of the ceasefire in Sudan and the Jeddah Declaration by both the army and the Rapid Support Forces. The two countries said that the violations have harmed civilians and the Sudanese people, and are impeding the delivery of humanitarian aid and the restoration of basic services. “Once it becomes clear that the parties are actually serious about complying with the ceasefire, the facilitators are prepared to resume the suspended discussions to find a negotiated solution to this conflict,” the Kingdom and the US said in a statement. They urged both parties to seriously commit to the ceasefire and support humanitarian efforts that respond to the humanitarian needs of the Sudanese people. Earlier on Thursday, the White House announced that it will impose sanctions against key defense companies and people who “perpetuate violence” in Sudan as the warring sides failed to abide by a cease-fire agreement.
