Australian aid worker escapes gunfire at Gaza checkpoint

She was with UNICEF colleagues in a convoy of three cars at a Wadi Gaza checkpoint at 10.30am on April 10 when "gunfire broke out in the vicinity", Ms Ingram told Al Jazeera.

"The gunfire came from the direction of the checkpoint towards civilians who then ran away from the checkpoint and the gunfire hit us," she said.

"We were very really lucky.

"We had some colleagues outside of the car checking a mechanical problem with the nutrition truck when the fire broke out and they had to run back to our armoured vehicle.

"Fortunately they were safe but three bullets hit the car that I was in, right on my passenger door, the window and also the bonnet of the car.

"So this is just another example of how unsafe it is for humanitarian aid workers and how missions like these are made impossible."

The UNICEF mission aimed to deliver a truck with ready-to-use therapeutic treatments and high-energy biscuits, Ms Ingram said in a video for the aid organisation.

The convoy included a truck of fuel needed to replenish water sources for the people of North Gaza.

"They're the sorts of delays that stop us from implementing our programmes, delivering aid and doing our jobs," Ms Ingram said.

"But we're not gonna give up. We're gonna try again, hopefully later this week," she said.
