Israel struck Nasser Hospital at least four times during its deadly attack in southern Gaza on Monday, an analysis of new video footage by BBC Verify has found.
The attack, which has attracted international condemnation and widespread anger, reportedly killed at least 20 people, including five journalists.
Initial reports from Gaza said that Israel had struck the hospital twice, with the first blast followed nine minutes later by another which hit first responders and journalists who arrived at the scene.
But new analysis suggests the hospital was struck four times in total. BBC Verify and expert analysis found that two staircases were hit almost simultaneously in the first wave, and while what was thought to be a single later attack was in fact two separate strikes hitting the same place within a fraction of a second.
Israel does not allow international journalists to enter Gaza independently. BBC Verify identified the additional strikes by analysing dozens of videos provided by a freelancer on the ground and material filmed by eyewitnesses that circulated online.
