PORT SUDAN: Air strikes and shelling rocked Khartoum on Thursday as the army attacked paramilitary positions across the Sudanese capital, witnesses and a military source said. The clashes began at dawn, several residents reported, in what appeared to be the army’s first major offensive in months to regain parts of the capital controlled by the rival paramilitary Rapid Support Forces. It comes the same day Sudan’s de facto leader, army chief Abdel Fattah al-Burhan, addressed the UN General Assembly in New York. On the eve of his address, UN chief Antonio Guterres voiced concern to Burhan “about the escalation of the conflict in the Sudan”, the United Nations said. The attack coincided with Sudan de facto leader’s speech at the UN General Assembly Burhan called in his address for the “rebel militia to be designated as a terrorist group” and accused the RSF of obstructing peace efforts. On the ground, Sudanese army forces were “waging fierce fighting against the rebel militia inside Khartoum”, a source in the military said, referring to the RSF. The source said army forces had crossed three key bridges over the Nile — which had separated parts of the capital held by the army from those under RSF control. Since April 2023, when war broke out between Burhan’s Sudanese Armed Forces and his former deputy, RSF commander Mohamed Hamdan Daglo, the paramilitaries had largely pushed the army out of Khartoum. In its last major offensive in February, the army regained much of Omdurman, the capital’s twin city across the Nile and part of greater Khartoum. The government loyal to the army is based in Port Sudan on the Red Sea coast, where the army has retained control. The RSF meanwhile has taken control of nearly all of the vast western region of Darfur, rampaged through the agricultural heartland of central Sudan and pushed into the army-controlled southeast. In his address at the UN, Burhan accused “countries in the region” of providing the RSF with “financial support, mercenaries and political cover”. The army chief did not name the countries, but his government has repeatedly accused the United Arab Emirates of funnelling arms to the paramilitaries from neighbouring Chad in violation of the arms embargo on Darfur. United Nations experts last year found the accusations “credible”, and diplomats say the United States has in private pressed the UAE over its support to the RSF.
