Australian doctor Mohammed Mustafa has returned from his second volunteer mission in Gaza, where he worked where he could to try and save lives amongst Israel’s bombardment of civilians.

He received a heroes welcome from supporters when he arrived back in Australia and has spent the days since trying to get Australian politicians to act.

He tells the ABC:

There was a particular incident that happened that night. I was covered in blood. We have to carry IDs with us 24 hours, and when I pulled out my Australian passport it was covered in blood and I couldn’t help but remember Zomi [Frankcom], the Australian aid worker who was killed and when they found her, her passport was covered in blood as well.

She hasn’t had any justice for what’s happened to her.

I reached out to her family and they’ve given me their blessing to carry that cross forward and go out there and fight for Zomi and Zomi died trying to feed children in Gaza and not just Gaza. She fed children all around the world and I want to do something in honour of Zomi and I want the government to help me, not just Zomi, but her family, to do something for her and honour her legacy. She died feeding those kids in Gaza and I feel like I let down those kids and I want to do this for her.
