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.
How the attack unfolded
The first strike hit at around 10:00 local time, medical staff at Nasser said.
There was mass panic... chaos, said a British medical professional working at the hospital, who was treating patients in the intensive care unit at the time.
Approximately 10 minutes later there was another blast in the same spot, the medical professional said, adding that medical staff had been planning their escape from the building when the second strike hit.
The hospital's emergency department, inpatient ward, and surgical unit were hit, according to the World Health Organization. Its head Dr. Tedros Adhanom Ghebreyesus said the emergency staircase was also damaged.
A livestream by Al Ghad TV shows several emergency workers responding to the first strike near the top floor of Nasser Hospital, as a number of journalists in the background film what's happening. A strike then directly hits the emergency workers and reporters, sending smoke and rubble in the air.
Wider reaction to the killings
UN Secretary General António Guterres strongly condemned the horrific killings at Nasser hospital, which he said highlight the extreme risks that medical personnel and journalists face as they carry out their vital work amid this brutal conflict, and called for a prompt, and impartial investigation.
UK Foreign Secretary David Lammy said he was horrified and called for an immediate ceasefire. French President Emmanuel Macron called the strikes intolerable and emphasized the need for the protection of civilians and journalists.
