Gaza aid convoy strike: What we know.

The group of World Central Kitchen (WCK) aid workers were travelling in three cars - two of them armoured.

They were part of a convoy delivering more than 100 tonnes of food supplies from a recently constructed pier to a warehouse in Deir al-Balah in central Gaza, according to WCK.

It says their movements had been co-ordinated with the IDF in advance but the investigation has found that this information had not been shared with Israeli drone operators tracking the convoy.

The IDF says they had spotted a gunman riding on the roof of a large aid lorry, that was being escorted by the WCK team. Drone footage of this was shown to journalists at an IDF briefing on 4 April but has not been released.

The IDF says the convoy was tracked to a warehouse (labelled 'A' on the map) where the aid lorry remained and four "SUV-type cars" emerged. It says one contained gunmen - also shown to journalists in drone footage - and headed north but was not targeted because it was close to another aid facility (labelled 'B').

The three remaining vehicles, belonging to WCK, headed south.

The investigation says "one of the commanders mistakenly assumed that gunmen were inside the accompanying vehicles and that these were Hamas terrorists".

The drone operators, the IDF says, had "misidentified" one of the aid workers as a gunman - they thought he was carrying a gun when he entered one of the cars but he was holding a bag. The IDF has not shown this footage.

The cars were then targeted.
