Chaos is taking hold in Gaza as smuggling bands form and add to the difficulties in delivering aid, the head of the United Nations Palestinian refugee agency has said.
UNRWA Commissioner-General Philippe Lazzarini said it had become "excruciating" to deliver supplies and voiced concerns that such conditions would impact efforts to counter the high famine risk confirmed by a global hunger monitor's report.
"Basically, we are confronted nowadays with a near total breakdown of law and order," Mr Lazzarini said, blaming in part an increase in gangs who are attacking aid trucks in the hopes of finding smuggled cigarettes stashed among aid supplies.
"It's becoming more and more complicated (to deliver aid)," he added.
Local police are refusing to escort aid convoys for fear of being killed, Mr Lazzarini said, while humanitarian truck drivers were regularly being threatened or assaulted.
Among the other challenges, he highlighted a near-drought in fuel supplies which brought the UNRWA vehicle fleet to a halt yesterday.
Israel vets such shipments into Gaza and has long maintained that there is a risk they are diverted to Hamas.
"We need sustainable, meaningful, uninterrupted aid in the Gaza Strip if we want to reverse the hunger situation," Mr Lazzarini said, adding that the operating environment is not conducive to doing so.
Israel says it has expanded efforts to facilitate aid flows and blames aid agencies for distribution problems in the territory.
Established in 1949 following the first Arab-Israeli war, UNRWA provides services including schooling, primary healthcare and humanitarian aid in Gaza and the region.
Earlier this year, 16 countries paused payments to the agency following Israel's claims that some of its staff were linked to Palestinian armed groups.
Mr Lazzarini said all but two of those countries, the United States and the UK, had since resumed financing after a review of the agency's neutrality showed Israel had yet to provide evidence for its accusations.
It now has enough funding to finance operations until the end of August, he added.
Ten children per day losing legs in Gaza - UNRWA
Ten children a day are losing one or both of their legs in the war in Gaza, Mr Lazzarini also said.
"Basically we have every day ten children who are losing one leg or two legs on average."
Citing figures from the United Nations children's agency UNICEF, he said that number "does not even include the arms and the hands, and we have many more" of these.
"Ten per day, that means around 2,000 children after the more than 260 days of this brutal war," Mr Lazzarini said.
Amputation often takes place "in quite horrible conditions, and sometimes without anaesthesia," he added, and children in Gaza are paying a "high price".
Mr Lazzarini pointed to findings published by Save the Children yesterday that up to 21,000 children are estimated to be missing in the territory.
At least 17,000 of them are believed to be unaccompanied and separated, while around 4,000 are likely missing under the rubble and an unknown number are believed to be in mass graves, the report said.
Those numbers come in addition to the thousands of children who figure among those who have died in the Israeli military operation in Gaza.
