David Albright, a world-renowned American nuclear expert and president of the Institute for Science and International Security, noted that "the Institute has identified new activity in recent days at one of the tunnels of the nuclear facility in Isfahan." He wrote this on his X account, adding that "vehicles were seen near the tunnel entrance, which was previously blocked due to attacks in the area." He further noted that heavy equipment could be identified at the middle tunnel entrance, "but there doesn't seem to be significant progress in accessing the tunnel entrance." Finally, he mentioned that minimal activity was observed around the destroyed buildings at the above-ground sites at the main Isfahan site.
