While some lorries as well as donkey carts have continued to distribute water in recent days, the ramping up of Israel's military offensive and new waves of displacement - affecting some 140,000 people in the north and south of the strip - have made this even more challenging.The UN's Office for the Co-ordination of Humanitarian Affairs (Ocha) says that water and sanitation services have already been severely disrupted by ongoing fuel shortages.

In northern Gaza, no fuel is currently available and only half the needed supply was received last week, Ocha says. This has meant the operating hours for water wells have been further reduced with complete shutdowns expected.In southern Gaza, Ocha says that UN water utilities have not received any fuel, although 140,000 litres of fuel per week are needed to keep them going. This has led to water, sanitation and hygiene facilities reducing their operating hours by more than one fifth.UN workers have said they try daily to retrieve fuel from reserves in areas where they are required to co-ordinate with the Israeli authorities, such as Rafah - which has been a main focus of military operations. However, these continue to be denied.

No new fuel has been allowed into Gaza since Israel imposed its full blockade on 2 March.A kidney specialist at al-Shifa hospital in Gaza City, Dr Ghazi al-Yazji, told the BBC he was seeing more patients with new infections and conditions caused by contaminated water and drinking water with high salinity.

"We don't have precise figures, but the cases are noticeably higher among children," he said.

Even before the war, shortages of water and the poor quality of supplies in Gaza contributed to relatively high numbers of patients with serious kidney complaints.The agreement also includes a £40m trust fund to support Chagossians.

Under the deal, although Mauritius will control Diego Garcia, it will not be allowed to resettle the island.Bernadette Dugasse is one of two Chagossian women, born on Diego Garcia, who brought a last-minute legal challenge over the deal to the UK's High Court. She

: "I don't belong in the UK, I don't belong in Mauritius, I don't belong in the Seychelles. I belong in Diego Garcia."Their legal challenge had temporarily blocked the deal when a court injunction was granted, but the High Court went on to dismiss the challenge.
