On March 23rd, the death toll in Gaza surpassed 50,000 people killed by Israeli fire in the war with Hamas.

This is the story of 15 people who were killed the same day.

It was just five days after Israel had ended a ceasefire and resumed attacks on Gaza.

There were airstrikes across the territory.

In the south, Israeli troops advanced on the ground, which is where they encountered the crew of emergency workers and ambulances and a fire truck.

The troops opened fire and killed the 15 paramedics and rescue workers.

At first, the Israeli military said the vehicles were advancing suspiciously toward troops without headlights or emergency signals.

It said the soldiers had eliminated a number of Hamas and Islamic Jihad militants.

And that is where the story might have ended.

Except a recording was unearthed days later from the phone of one of the paramedics,

and it disproved the Israeli military's account.

That showed very clearly the cars, the vehicles of the ambulances had their lights on,

the fire brigade truck had its lights on, and the silence. You hear the sound.

That's Marwan Jalani, vice president of the Palestinian Red Crescent Society. He said his organization

had presented the video to the United Nations Security Council and called for an independent

investigation. We have never seen an Israeli investigation that resulted in any accountability whatsoever.

After the video became public, Israel did conduct an investigation and release the results over the weekend.

It blamed the killings on an operational misunderstanding

and cited professional failures. Consider this. In more than 18 months of war, it has been rare for

the Israeli military to acknowledge failure. Coming up, we hear from one of the survivors of the attack.
