"Visible from space" used to mean "by astronauts". If high-resolution sensors are allowed, then the term applies to things like a tree and a car, and doesn't signify much.
Well, maybe it signifies that nobody wants to go and take photos in person.
"Analysis by the Yale School of Public Health Humanitarian Research Lab (HRL), which has been tracking the siege using open source images and satellite imagery, found clusters of objects “consistent with the size of human bodies” and “reddish ground discolouration” thought to be either blood or disturbed soil."
The "visible from space" here is clearly dumb click bait from The Telegraph.
