The attack on the hospital came just after 10 a.m. local time on Monday when a balcony at the Nasser Hospital in Khan Younis was hit by what appears to be a tank shell, killing a Reuters cameraman and others. Nine minutes later, as a group of rescue workers and other journalists attended to the victims, they were hit as the Israeli military fired again on the hospital – a tactic known as a “double tap.”

New video obtained by CNN reveals that this second “tap” was in fact two near-simultaneous strikes. These second and third strikes appear to have caused most of the deaths.

Intentionally attacking rescue workers, journalists and other civilians is a violation of international humanitarian law and a war crime.
