RAFAH: UN relief workers on Thursday reported “unbearable” scenes in two hospitals in northern Gaza, where bedridden patients with untreated wounds cry out for water, the few remaining doctors and nurses have no supplies, and bodies are lined up in the courtyard — signs of the worsening humanitarian crisis after 10 weeks of war. The relief workers spoke after delivering supplies a day earlier to Ahli and Shifa hospitals, which are located in the heart of the north Gaza battle zone where Israeli troops have demolished vast swaths of the city while fighting Hamas militants. Bombardment and fighting continued on Thursday, but with Gaza’s internet and other communications cut off for a second straight day, details on the latest violence could largely not be confirmed. With supplies to Gaza cut off except for a small trickle, the World Food Programme has said 90 percent of the population regularly goes without food for a full day. A blast on Thursday morning hit the Palestinian side of the Kerem Shalom crossing from Israel into Gaza, forcing the UN to stop its pickups of aid there, according to Juliette Touma, spokesperson of UNRWA, the UN agency for Palestinian refugees. At least four people were killed, the nearby hospital reported. Israel had begun allowing aid to enter Gaza through Kerem Shalom only days earlier for the first time in the war, under pressure from the US to ensure more help gets to Palestinians. Palestinian authorities blamed Israel for the blast. Only nine of Gaza’s 36 health facilities are still partially functioning — and all are located in the south, the World Health Organization said. In the north over recent weeks, Israeli forces have raided a series of health facilities, detaining men for interrogation and expelling others. In other facilities, patients who are unable to be moved remain along with skeleton staff.
