(MENAFN) US Secretary of State Marco Rubio called Wednesday for decisive international action to sever weapons pipelines sustaining Sudan's paramilitary Rapid Support Forces, warning that humanitarian collapse accelerates as the militia consolidates territorial control and perpetuates mass atrocities.

Rubio issued the demand following a G7 foreign ministers gathering in Niagara, Canada, where he briefed journalists on escalating civilian suffering and systemic RSF violations. The US State Department chief characterized the deterioration as requiring immediate coordinated intervention.

"I think something needs to be done to cut off the weapons and support that the RSF is getting as they continue with their advances," Rubio told reporters.

Rubio disclosed that Washington has engaged Egypt, Saudi Arabia and the United Arab Emirates in multilateral pressure campaigns targeting external weapons suppliers. He underscored the intensity of diplomatic efforts without publicly identifying specific offenders.

"Pressure is being applied to the relevant parties," he stated, while declining to designate particular nations or entities. Rubio reiterated the strategic imperative, declaring: "I don't want to get into calling anybody out in a press conference today, because what we want is a good outcome here. This needs to stop."

The State Department official emphasized the geopolitical dimensions of the weapons flow, characterizing external military assistance as deliberately sustaining RSF operations. "They're clearly receiving assistance from outside...and that needs to stop," he stressed.

Rubio described Sudan's humanitarian landscape with stark language, invoking "horrifying" conditions documented by aid organizations. He cited unprecedented malnutrition rates and suffering concentrations among displaced populations—metrics unprecedented in recent humanitarian emergencies.

Rubio characterized RSF conduct as exhibiting systematic brutality patterns, accusing the militia of chronic non-compliance with negotiated agreements. "The RSF agrees to things and never follows through with it," he said, underscoring the group's documented atrocities.

RSF adviser denounces US pressure
El-Basha Tibeig, a strategist advising RSF commander Mohamed Hamdan Dagalo, rejected Rubio's characterization as counterproductive. Tibeig framed the State Department statement as "an unfortunate step" undermining the US-led Quad's nascent humanitarian diplomacy initiative aimed at establishing a ceasefire framework.

The US, Saudi Arabia, UAE, and Egypt constituted the Quad coalition, which on Sept. 12 formally proposed a three-month humanitarian moratorium enabling unrestricted emergency relief distribution across contested territories—conceptualized as a precursor to permanent hostilities cessation.
