The letter, dated March 29, calls for the full restoration of UK funding to UNRWA and unimpeded access of humanitarian aid into Gaza.

The MPs warn that Israel should face diplomatic consequences if it violates international law and restricts access to water and other essential resources.

They also demand that Israel abide by the provisional measures set by the International Court of Justice in January.

A letter signed by over 100 British lawmakers is putting pressure on the UK government to take action against Israel due to the ongoing conflict with Hamas in Gaza.

The letter sets a deadline for changes in British foreign policy towards Israel, threatening "serious consequences" if none are met.

Chris Doyle, director of the Council for Arab-British Understanding, called the letter a "turning point" and evidence of growing anger in political circles over the UK's response to the violence.

The letter also accuses Israel of hindering the UK's humanitarian aid efforts in Gaza.

The text expresses concern over Israel's delay in allowing UK aid into Gaza by denying border crossings and visa applications for necessary staff.

The civilian population in Gaza is at risk of famine, with children and adults already having died from starvation or dehydration.

People are forced to eat unconventional foods like bird seed, animal feed, and grass, and dig up water pipes for drinking and washing.

The UK government has officially blamed the Israeli government for the failure of humanitarian aid reaching Gaza due to arbitrary denials.

In February, the UK government issued a warning that Israel could violate international humanitarian law by denying food and water to Gaza.

This came after a UN Security Council vote calling for an immediate ceasefire in Gaza, which the UK supported.

The UK's stance towards Israel may change due to the threat of an invasion of Rafah, where most of Gaza's population is sheltering.

Any incursion into this area could lead to a strong response from the UK and European powers.
