UN Secretary-General Antonio Guterres has described the current situation in Sudan as "deeply concerning," reiterating his warnings of the conflict spreading to neighboring countries. Guterres spoke at a press conference in Nairobi, Kenya, and addressed the developments in Sudan and the clashes that began on April 15 between the Sudanese army, led by Lt- Gen Abdel Fattah al-Burhan, and the Rapid Support Forces of Mohammed Hamdan Dagalo. He explained that several agreements failed to stop the fighting that has driven tens of thousands of refugees out of Sudan and raised fears of a deepening humanitarian crisis in the region. The envoy asserted that the parties should agree on a lasting ceasefire, saying the situation is profoundly concerning, fearing that it could extend to neighboring countries going through political problems and transitional stages. He expressed concerns with Chad, asserting the need to support the country in the present situation, saying Ethiopia is in a peace process, and it is essential to avoid any spillover from Sudan to Ethiopia. Guterres dispatched UN emergency relief coordinator Martin Griffiths to Port Sudan, where thousands of Sudanese and foreigners gathered, hoping to flee the country. Upon arriving in Port Sudan, Griffiths tweeted that his visit reaffirmed the UN's commitment to the Sudanese people. The envoy sought to organize the dispatch of humanitarian aid to the millions of Sudanese stranded in combat zones, with the continuation of Arab and international efforts to reach a sustainable cessation of war operations. Thousands of UN staff have been evacuated via a road convoy to Port Sudan, and some UN offices temporarily suspended their services, such as the World Food Program (WFP), after two of their staff were killed in the fighting. Later, the program announced that it would resume operations and food distribution is expected to begin in four states - Gedaref, Gezira, Kassala, and White Nile, in the coming days. Griffiths said in a press conference from Port Sudan that he seeks solid guarantees on the safety and security of aid workers and supplies. He addressed criticism that the UN had not done enough, saying it was challenging to operate in Sudan, saying that six of the WFP trucks traveling to the western region of Darfur had been looted en route, despite assurances of safety and security. "It's not as if we're asking for the moon," he said, adding: "We're asking for the safe movement of humanitarian supplies and people. We do this in every other country, even without ceasefires." "We are very clear now in our operational requirements as to what we need in terms of commitments from them," he said. Griffiths' visit came after the South Sudanese Ministry of Foreign Affairs announced that the two parties to the conflict had agreed "in principle," to a seven-day ceasefire starting Thursday. The United Nations announced that its dedicated programs had secured only 14 percent of the funds required for its operations for this year in Sudan, and it still needs about $1.5 billion to meet these needs, which have been exacerbated since the outbreak of the fighting. - Dead, wounded, and displaced The conflict has killed 550 people, including civilians, and injured more than 4,900. At least 334,000 people were displaced inside Sudan, and tens of thousands have fled to neighboring countries such as Egypt, Chad, South Sudan, the Central African Republic, and Ethiopia. However, these numbers still need to be revised and are likely to rise steadily if the fighting continues. The UN Refugee Agency reported that more than 42,000 Sudanese have crossed into Egypt, along with 2,300 foreigners. Aid workers are increasingly concerned about the lack of essential services in combat zones. Several Western countries have completed evacuations of their citizens from the country, and France, Britain, and the Us are now using Port Sudan as a base for those looking to leave. But citizens of other countries are still struggling to find a way out. Furthermore, the Saudi warships carry mainly foreigners, Sudanese of dual citizenship, and others across the Red Sea to Jeddah in Saudi Arabia.
