Israel is facing fierce condemnation after a pair of strikes on a Gaza hospital killed five journalists as well as medical workers and others on Monday.

Israeli Prime Minister Benjamin Netanyahu’s office said the strike on Nasser Hospital was a “tragic mishap” and that the military was investigating.

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.
