The young journalist shot drone images and video for Ain Media, a small Gaza-based news agency he started five years ago. Just two weeks ago, he posted an aerial photo of Gaza City’s port on Facebook. “I wish that the day would come to take this shot when I’m in the air and not on the ground,” he wrote. “My name is Yaser Murtaja. I’m 30 years old. I live in Gaza City. I’ve never traveled!”

It was one of his last posts.
