The UN decried Friday the intentional destruction of complex and hard-to-obtain medical equipment in Gaza's beleaguered hospitals and maternity wards, further deepening risks to women already giving birth in "inhumane, unimaginable conditions".

Recent United Nations-led missions to 10 Gaza hospitals found many "in ruins" and just a couple capable of providing any level of maternal health services, said Dominic Allen, the UN Population Fund (UNFPA) representative for the State of Palestine.

He said that what the teams found at the Nasser hospital complex, long besieged by Israeli forces during their operations in the southern city of Khan Yunis, "breaks my heart".

Speaking to journalists in Geneva via video-link from Jerusalem, he described seeing "medical equipment purposefully broken, ultrasounds -- which you will know, is a very important tool for helping ensure safe births -- with cables that have been cut".

"Screens of complex medical equipment, like ultrasounds and others with the screens smashed," he added.

The World Health Organization has described the difficulty of bringing such equipment into Gaza even before the current war erupted following Hamas's October 7 attack inside Israel.

Meanwhile at Al-Khair, another specialized maternity hospital in Khan Yunis, "it didn't seem as if there was any piece of working medical equipment", he said, lamenting that the birthing rooms "stand silent".

"They should be a place of giving life and they just have an eerie sense of death."

Only 10 of Gaza's 36 hospitals are currently even partially functioning.

Allen said that only three of those were now capable of assisting the estimated 180 women giving birth across Gaza every single day -- around 15 percent of whom suffer complications requiring significant care.

The hospitals that can provide such care are thus facing significant capacity constraints.

The Emirati Hospital in the south, which is the main maternity hospital in Gaza currently, is for instance supporting up to 60 births every single day, including as many as 12 Caesarian sections, he said.

Given the heavy pressure on the facility, women are discharged just hours after giving birth, "and after C-sections, it is less than a day", Allen said, stressing "that increases risks".

The current war started after Hamas launched its unprecedented attack on October 7 that resulted in the deaths of 1,170 people in southern Israel, mostly civilians, according to an AFP tally of Israeli official figures.

The militants also took about 250 hostages. Israel estimates 129 remain in Gaza, including 34 who are presumed dead.

Israel's retaliatory offensive has killed at least 33,970 people in Gaza, mostly women and children. according to the Hamas-run territory's health ministry.
