Palestinians queue outside the pharmacy of a clinic run by the UN aid agency for Palestinian refugees(UNRWA) in al-Shati refugee camp west of Gaza City, where shelves are running low amid a worsening health crisis due to the lack of necessary medications for treatment. "I need monthly treatment, but I never receive the full course — only enough for ten days or two weeks," says Akram al-Khatib, a diabetic patient and school teacher, adding that Palestinians are "suffering severely due to the shortage of medicine." Israel blocked the entry of all aid into the Palestinian territory of around 2.4 million people days before it resumed its aerial and ground offensive after the collapse of a two-month ceasefire with Hamas.
