North Korea may have taken additional steps towards dismantling its Sohae Satellite Launching Station.
According to 38 North satellite images of the site from July show the regime had made some changes to the roof of a fuel structure on the launch pad.
It was smooth and flat in March and May, but in July there appeared to be roof work and objects on it.
The activity has ceased, since then.
The U.S.-based North Korea monitoring website adds, because of the low image quality, they can't be completely sure those changes are relevant to the structure's dismantling.
But if confirmed, 38 North pointed out this would be another major step for Pyeongyang in keeping its promise.
