Hospitals in Gaza and other vital medical infrastructure have been attacked nearly 600 times since war erupted in the enclave in response to the Hamas-led terror attack in southern Israel, the UN health agency said on Friday.
Some 613 people have died within facilities as a result since 7 October last year and more than 770 have been injured, according to latest data on healthcare attacks from the World Health Organization (WHO).
Condemning the continuing fighting and bombardment, WHO spokesperson Christian Lindmeier said that the "ongoing reduction of humanitarian space plus the continuing attacks on healthcare are pushing the people of Gaza to breaking point".
Children in the Gaza Strip face a deadly triple threat to their lives, as cases of diseases rise, nutrition plummets and the escalation in hostilities approaches its fourteenth week.
Thousands of children have already died from the violence, while living conditions for children continue to rapidly deteriorate, with increasing cases of diarrhea and rising food poverty among children, raising the risk of mounting child deaths.
Hundreds of facilities hit
WHO's online platform covering attacks on healthcare indicated that more than 550 medical facilities and vehicles had been impacted in the almost 100 days since constant Israeli airstrikes began in Gaza.
The attacks have affected 94 healthcare sites including 26 hospitals damaged out of a total of 36 in the enclave.
'Nightmare' conditions for children: UNICEF
The head of the UN Children's Fund UNICEF said in a statement on Friday that children in Gaza "are caught in a nightmare that worsens with every passing day".
Catherine Russell noted young lives are "increasingly at risk from preventable diseases and lack of food and water. All children and civilians must be protected from violence and have access to basic services and supplies."
Cases of diarrhoea in children under five rose from 48,000 to 71,000 in just one week starting 17 December, equivalent to 3,200 new cases of diarrhea per day.
She said the significant increase indicated child health in Gaza is "fast deteriorating". Before the escalation in hostilities, an average of 2,000 cases of diarrhea in children under five were recorded per month.
Relief effort stymied
In a statement released by Eri Kaneko, Spokesperson for aid coordination office OCHA, humanitarians made clear on Thursday that the speed and volume of relief is being continually hampered by conditions on the ground.
"The UN and our humanitarian partners are committed to and continue to do all they can to meet the growing needs in Gaza. However, the operating environment and response capacity continues to be hindered by security risks, mobility constraints, delays and denials", she said.
"Multiple inspections, long queues of trucks and difficulties at crossing points continue to hamper operations. Inside Gaza, aid operations face constant bombardments, with aid workers themselves killed and some convoys having been shot at.
Se made clear other challenges include poor communications, damaged roads and delays at checkpoints.
"An effective aid operation in Gaza requires security, staff who can work in safety, logistical capacity and the resumption of commercial activity."
142 UNRWA staff killed
Meanwhile, the UN agency providing help to Palestinians, UNRWA, said that the total number of staff killed since the beginning of hostilities stands at 142.
The UN Relief and Works Agency for Palestine Refugees also reported that since 7 October last year, up to 1.9 million people have been displaced across the Gaza Strip, some multiple times.
This number represents over 85 per cent of the population of the Gaza Strip, UNRWA said, adding that families have been forced to move "repeatedly in search of safety".
Nearly 1.4 million internally displaced persons (IDPs) now shelter in 155 UNRWA facilities across all five governorates of the Gaza Strip.
This figure includes 160,000 in the north and Gaza City according to data last revised shortly after the escalation began.
Another 500,000 people "are in close vicinity of these installations and receiving assistance" from UNRWA, the UN agency said in an update.
IOM launches $69 million appeal
The UN's migration agency IOM launched an urgent appeal on Friday for $69 million to support its response to rising and critical humanitarian needs in the Occupied Palestinian Territories.
The appeal also covers neighbouring countries affected by the ongoing hostilities in Gaza.
In a statement, IOM said that hundreds of thousands of civilians need aid desperately. But getting help to them continues to be hampered by "long clearance procedures for humanitarian aid trucks at the border (and) the intense ground operation and fighting".
"Frequent disruption" to communication networks has also prevented humanitarian aid coordination, the UN agency said "along with insecurity, blocked roads and scarcity of fuel".
Outside Gaza, IOM noted that deteriorating security situation along border areas between Israel and Lebanon has forced some 76,000 people from their homes in southern Lebanon.
