Witnesses say Israel has struck southern Gaza’s main hospital with a missile and then fired another as journalists and rescue workers rushed to the scene, killing at least 20 people.

The Hamas-run health ministry in Gaza has this morning reported at least 20 deaths following an Israeli strike on the Nasser hospital in Khan Younis. The ministry says that medics, patients and journalists are among those who have died, and says that treatment of patients in the hospital has been impacted.

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