UNITED NATIONS, May 5 (Xinhua) -- UN humanitarians on Tuesday warned that civilians in Gaza continue to come under fire, as strikes and exchanges of gunfire hit residential areas.

The UN Office for the Coordination of Humanitarian Affairs (OCHA) said its partners reported that last week saw one of the highest numbers of security incidents since the ceasefire was declared in October 2025.

Humanitarian facilities came under fire in two separate incidents. An airstrike also struck near a UN warehouse and relief vehicles were damaged by stone throwing, said OCHA.

Restrictions on the entry of engine oil, spare parts, rubble-removal machinery and other essential items into Gaza are severely impacting the delivery of critical services, said the office.

"Vehicles and generators are breaking down beyond repair, disrupting food distribution, water trucking, ambulance services and the delivery of educational supplies and medical items. Generator failures are also affecting hospitals, including intensive care units," OCHA said. "As armoured vehicles become increasingly worn out, aid workers are facing growing risks as they work to reach people in need."

The office reminded that, in line with international humanitarian law, all parties must fulfill their obligation to facilitate, not obstruct, humanitarian operations. Civilians and civilian infrastructure must always be protected. ■
