Global Crises Deepen: Russia-Ukraine Talks Stall, Sudan Refugee Emergency Worsens, Colombia Faces Surging Displacement.

Diplomatic efforts and humanitarian responses are being tested worldwide as three major crises unfold: stalled peace talks between Russia and Ukraine, a worsening refugee emergency in Sudan and Chad, and a dramatic rise in displacement in Colombia.

For the first time in three years, Russian and Ukrainian delegations met face-to-face in Istanbul to discuss a possible ceasefire and a large-scale prisoner exchange. The meeting, supported by Türkiye and the United States, was seen as a critical step towards peace. U.S. President Donald Trump announced that both sides had agreed to begin negotiations “immediately” for a ceasefire and an end to the war, with Russian President Vladimir Putin expressing that the process was “on the right track”. The talks resulted in an agreement to exchange 1,000 prisoners from each side—the largest such swap so far. However, no agreement was reached on a ceasefire, as Russia insisted on conditions that Ukraine and its allies consider unacceptable, such as withdrawal from occupied territories. The level of participation at the talks, with neither Putin nor senior Russian officials present, raised doubts about Moscow’s seriousness. A Turkish official noted, “Russia’s representatives made it clear that an unconditional ceasefire was not up for discussion.” Despite the symbolic importance of the talks, both sides remain far apart, and hopes for a quick end to the war are slim.

Sudan Exodus: Refugee Crisis Reaches New Highs
Meanwhile, the humanitarian situation in Sudan and neighboring Chad has reached a critical point. Escalating violence, especially in Darfur, has driven more than 20,000 refugees into Chad in May 2025 alone, with women and children making up the majority. The United Nations reports that Chad now hosts about 1.3 million refugees, including almost 800,000 Sudanese who have fled since the civil war reignited in April 2023. Many refugees have suffered serious abuses during their flight, including assault and sexual violence. “This is the worst situation I have encountered in my entire decades of career as humanitarian,” said the head of the UNHCR office in Chad. Inside Sudan, over 11 million people are displaced, and nearly half the population is in need of humanitarian aid. UN agencies warn that famine, disease, and lack of shelter are compounding the crisis, and funding gaps are making it even harder to meet urgent needs. The UNHCR and partners are struggling to provide enough food, water, and protection, especially as the rainy season brings new health risks.

Colombia: Displacement Surges Amid Renewed Violence
In Colombia, violence between armed groups has forced over 66,000 people from their homes since January 2025—a 28 percent increase over last year. The Catatumbo region, near the Venezuelan border, has seen some of the worst fighting and mass displacements in decades, with more than 56,000 people forced to flee in just a few weeks. The UN Office for the Coordination of Humanitarian Affairs (OCHA) reports that 7.3 million Colombians remain displaced within the country, the third largest number globally after Sudan and Syria. Humanitarian agencies are struggling to meet the needs of those affected, with only a fraction of required funding available. “We have not seen such a humanitarian crisis on this scale in Colombia in almost 30 years,” said Giovanni Rizzo, NRC’s country director in Colombia. Many displaced families are trapped without food or aid, and the government has declared a state of emergency in the hardest-hit regions. A displaced man from Catatumbo described the tragedy:

“To leave your roots because of war, to bury family lost to a conflict they didn’t choose, this is the tragedy we face.”

A Call for Global Action
These crises underscore the urgent need for sustained diplomatic efforts and humanitarian support. In Ukraine, peace remains elusive as both sides refuse to compromise on core issues. In Sudan and Chad, the refugee emergency is growing faster than aid agencies can respond. And in Colombia, decades-old conflicts continue to uproot families and threaten fragile peace efforts. As the UN and humanitarian groups warn, without increased funding and international cooperation, millions will remain at risk, and the hope for peace and stability will remain out of reach.
