A double Israeli strike on a hospital in Gaza killed 20 people including journalists and health workers, according to the outlets they worked for, the World Health Organization and the Hamas-run health ministry.
At least one person was killed in an initial strike, and others in a second attack minutes later as rescuers and journalists attended the scene at Nasser hospital in Khan Younis.
The five journalists worked for international media outlets, including the Associated Press, Reuters, Al Jazeera and Middle East Eye.
Later on Monday, Israeli Prime Minister Benjamin Netanyahu called the incident a "tragic mishap" which Israel "deeply regrets" and said military authorities were "conducting a thorough investigation".
The first strike hit at around 10:00 local time, medical staff at Nasser said.
