Military officials tell Hebrew-language media outlets that an Israeli army tank team shelled a camera stationed at Nasser Hospital in Khan Younis earlier today after believing the device was being used to track troops.

Two shells were fired by the tank, with the first targeting the camera and the second hitting rescuers who were operating at the scene. The strike killed 20, including five journalists, according to media reports and Hamas health officials.

Reuters and other news providers often deliver live video feeds to media outlets worldwide during major news events to show the scene from the ground in real time. A review of Masri’s live feed from before the strike did not appear to show any soldiers.
