Introduction

Recent events in the Yemen crisis stem from regional militaries, political groups, and diplomatic affairs. The ongoing civil war continues to play a role. This humanitarian emergency reveals how serious the current crisis is and its effects on the region.

Conflict Escalations

A series of major attacks in Yemen, retaliatory actions, and shifts in military strategy have reshaped the crisis and drawn increased attention from both regional and global actors, including the UNSC. These changes became especially evident in August 2025, when the Houthis launched cluster munitions into Israeli territory. This marked the first known instance of the group deploying Iran-backed weaponry directly against Israel. In response, retaliatory airstrikes were carried out. This escalated tensions further. Shortly after, the Israel Defense Forces (IDF) conducted strikes on a military complex in Yemen’s capital, Sana’a. This shows the rapid expansion of the conflict beyond its original scope. Six people were killed, and 86 were injured.

A week later, another bombing occurred on August 28, 2025. In this bombing, an Israeli airstrike killed the Houthi Prime Minister, Ahmed Ghaleb Nasser al-Rahawi, in Sana’a. He was replaced by Muhammad Ahmed Miftah, who held similar political beliefs to al-Rawahi. Israel’s Prime Minister Benjamin Netanyahu stated, “Anyone who attacks us – we attack them. Anyone planning to attack us – we attack them. I believe the entire region is learning the power and determination of the State of Israel.” In response, the Houthis fought back in September 2025 with drone strikes. The attacks breached the Israeli missile defense system and wounded 22 civilians in Eilat, Israel. Because of the Yemeni Prime Minister’s death and both sides fighting back, the situation has remained tense.

Tensions between the two sides continued to rise until the Houthis adopted a new approach. The Houthi-led Yemeni authorities began regularly targeting Israeli-linked shipping in the Red Sea, citing opposition to Israel’s actions in the Israel–Palestine conflict. Vessels connected to countries with close ties to Israel, including the United States and the United Kingdom, were also affected. This further expanded the scope of the conflict and increased international concern.

The UNSC had previously called for the Houthis to stop their attacks through Resolution 2739 (2024), but reports indicated the attacks continued throughout the summer and early fall of 2025. More recently, Yemeni authorities have reportedly reduced attacks on shipping vessels, a change that coincided with the implementation of the Israel–Hamas ceasefire in October 2025. The ceasefire is a three-phase plan aimed at ending hostilities, facilitating the exchange of hostages, supporting reconstruction, and reducing violence.

The Houthis have indicated that they will refrain from targeting Israeli-linked ships as long as the Gaza ceasefire holds. In a letter to Hamas, they signaled that they would resume if fighting restarts. These are not empty threats, as they have already sunk four ships and killed nine mariners since 2023. In response to these events, the United Nations has expressed concern over the conflict. Countries such as the US, UK, and 22 others have condemned the official Houthi government, supporting Israel’s right to self-defense.

Diplomatic and Humanitarian Concerns

In August 2025, UN staff in Sana’a were accused by the Houthis of spying for Israel and causing the bombings in Yemen. On August 31, 2025, the Yemeni government raided and detained workers in UN facilities in Sana’a. This was only a single day after the prime minister was confirmed dead in an airstrike. Initially, only 11 staff members were held hostage, but more facilities were raided, and more staff were arrested in the following months. The UN stated that at least 59 staff were being held unharmed in October 2025.

The Houthis then reported that they were going to put the staffers on trial and may escalate punishments to the death penalty. Despite the UN’s repeated denials of involvement in the situation, over 50 staff remain detained as of December 2025. Only a dozen were released from captivity. In November 2025, UN 18 workers were sentenced to death by firing squad. This was despite Secretary-General António Guterres renewing his call for the release of all staff. Thus, the hostage situation impairs the UN’s ability to engage with the crisis in Yemen.

The diplomatic and humanitarian impacts of the crisis are closely interconnected. The ongoing conflict has shaped United Nations engagement and created opportunities for external actors to influence the situation. The current circumstances highlight the continuing deterioration of living conditions in Yemen. Between August and December 2025, an estimated 49 percent of the population, approximately 17.1 million people, faced food insecurity. In addition, 47.4 percent of children under five years of age were reported to experience malnutrition, underscoring the severe humanitarian challenges in the country.

Yemen is projected to reach Integrated Food Security Phase Classification (IPC) Level Four: Emergency. This indicates that people can no longer meet their daily food needs. Currently, Yemen is the third most food-insecure country in the world. Because UN workers are detained, the UN’s ability to provide humanitarian aid has been limited. Tom Fletcher, the Under-Secretary-General for Humanitarian Affairs, has also called for all workers to be released. The current conflict demonstrates how diplomatic actions can aid the crisis. This shows a need for effective and timely solutions.

Conclusion

The current situation in Yemen is getting worse and moving toward increased conflict. The crisis has intensified the long-term effects of humanitarian distress. It has also influenced internal and external actors. Yemen’s internationally recognized government receives support from the Saudi-led coalition, while the Houthis maintain backing from Iran. The conflict has implications that extend beyond the region, and continued hostilities pose significant risks to civilians. Those affected face severe humanitarian consequences. There is an urgent need for conflict de-escalation, expanded humanitarian assistance, and programs aimed at stabilization and protection of vulnerable populations.
