Hospital officials in Gaza say Israeli strikes and gunfire have killed at least 33 Palestinians sheltering in tents or seeking scarce food aid.

David Lammy has condemned the famine in Gaza as “utterly horrifying” and a “man-made catastrophe” caused by Israel.

Food-security experts said a famine has taken hold in the Gaza City area, the first-ever such determination in the Middle East and one that puts more pressure on Israel.

For an area to be experiencing famine, at least 30 percent of children under 5 must be considered acutely malnourished by height and weight measures. Using the arm circumference method, the I.P.C. said, the accepted threshold dropped to 15 percent.

Thousands of pro-Palestine supporters gathered Friday outside the Israeli Embassy in London to draw attention to the genocide and famine in the Gaza Strip, where the Zionist regime have been brutally bombing the besieged enclave and imposing a blockade.

A U.N.-backed food security group has issued a dire warning: famine has officially now taken hold in northern Gaza and is expected to spread in the coming months.

U.N. Humanitarian Chief Tom Fletcher said that the famine that has struck part of Gaza was preventable, blaming the "systematic obstruction" of aid by Israel and demanding that Prime Minister Benjamin Netanyahu let supplies in on a massive scale.
