In a unanimous statement, the 15-member council condemned the continued detention of UN staff, aid workers and civil society representatives, warning that the arrests are worsening Yemen’s already severe humanitarian crisis.

Council members said all threats against humanitarian personnel were unacceptable and stressed that those delivering aid must be allowed to operate safely and without obstruction.

The Houthis began a major detention campaign in June 2024, arresting staff from UN agencies, non-governmental organizations and diplomatic missions in areas under their control. Additional arrests were reported in 2025, leaving dozens detained without charge and with limited access to legal representation or family contact.

The Security Council reiterated that all parties to the conflict must comply with international humanitarian law and ensure safe, unhindered humanitarian access.

The council also reaffirmed support for UN Special Envoy Hans Grundberg and efforts to reach a comprehensive political settlement to Yemen’s long-running conflict.

According to the UN, more than 22.3 million people in Yemen currently require humanitarian assistance.

The incident occurred during routine water delivery at the Mansoura water filling point, a key facility supplying Gaza City, UNICEF said in a statement, adding that two other individuals were injured in the attack.The agency said it was “outraged” by the killings and stressed that humanitarian personnel, civilians and essential infrastructure must be protected under international humanitarian law.

It urged Israeli authorities to investigate the circumstances surrounding the incident.Israel’s embassy in Washington did not immediately respond to requests for comment.The development comes amid a fragile ceasefire between Israel and Hamas that has been in place since October, ending two years of full-scale conflict.

Despite the truce, Israeli forces remain deployed across a large depopulated zone covering more than half of the Gaza Strip, while Hamas continues to control the remaining coastal territory.Violence has persisted since the ceasefire, with local medics reporting more than 750 Palestinian deaths, while militants have killed four Israeli soldiers.

Both sides have accused each other of violating the terms of the truce.UNICEF said the suspension of activities at the water site could further affect access to clean water for civilians in Gaza, where humanitarian conditions remain severe.
