Palestinians flock to Gaza aid centres despite concerns - as lawyers call for sanctions on Israel

Thousands of Palestinians have flocked to aid distribution sites in Gaza with desperation for food overcoming concerns over Israeli-enforced checks at the centres.

The Gaza Humanitarian Foundation (GHF), which is backed by Israel and the US, said on Tuesday it had distributed around 8,000 food boxes, equivalent to about 462,000 meals - just a fraction of what is needed, aid agencies say. The centres have opened as hundreds of legal professionals in the UK, including lawyers and former judges, accused Israel of "genocide" and "war crimes".

Crowds including women and children could be seen at one centre in Rafah, southern Gaza, where people received packages including rice, flour, canned beans, pasta, olive oil, biscuits and sugar. Witnesses in Rafah said Israeli gunfire was heard after desperate people broke fences to reach supplies.

The Israeli military said its forces did not direct aerial gunfire towards the centre, but rather fired warning shots in an area outside the hub. In a statement, it said control over the situation had been established, with aid distribution to continue as planned.

Many Palestinians stayed away amid fears over Israel's plan to use biometric screening procedures on those receiving vital food packages. Israeli officials said one advantage of the new aid system is the chance to screen recipients to exclude anyone they say is connected with Hamas.

Humanitarian groups briefed on the plans say anyone receiving aid will have to submit to facial recognition technology - which many Palestinians fear will end up in Israeli hands to track and possibly target them. Father-of-seven Abu Ahmed said: "As much as I want to go because I am hungry and my children are hungry, I am afraid." He continued: "I am so scared because they said the company [GHF] belongs to Israel and is a mercenary, and also because the resistance [Hamas] said not to go." UN boycotts aid foundation Israel previously said its forces would not be involved in the distribution points but its endorsement of the plan, which resembles Israeli schemes floated previously, has led to many questioning the neutrality of GHF.

The United Nations and major international aid groups have refused to cooperate with the GHF - accusing it of undermining the principle that aid should be distributed based on need. "Humanitarian assistance must not be politicised or militarised," said Christian Cardon, chief spokesperson of the International Committee of the Red Cross.

The letter says "genocide is being perpetrated in Gaza or that, at a minimum, there is a serious risk of genocide".

It continues: "War crimes, crimes against humanity and serious violations of international humanitarian law are being committed." Israel has consistently denied these accusations. As a small flow of aid has arrived in Gaza after Israel's months-long blockade, Israeli forces have kept up attacks on various targets in the territory.

Some 3,901 Palestinians have been killed since a ceasefire collapsed in mid-March, according to Gaza's Hamas-run health ministry. As the GHF centres opened on Monday, Israeli airstrikes killed at least 36 people in a school-turned-shelter that was hit as people slept, according to local health officials.

Israel said it targeted militants operating from the school..
