The World Health Organization chief warns of a catastrophic situation in northern Gaza, with intensive military operations unfolding around and within healthcare facilities. The last functioning hospital in the area was stormed by Israeli forces, leaving two children dead and hundreds of staff, patients, and displaced people detained. The Gaza health ministry informed WHO that the siege had ended, but at a heavy cost. The whole health system in Gaza has been under attack for over a year, and WHO emphasizes the need to shield hospitals from conflict and calls for an immediate and unconditional ceasefire.
