Israeli troops appear to have advanced over two miles into Gaza, according to a CNN analysis of video published by an Israeli media outlet.
The troops in the video, taken on Saturday, are seen putting an Israeli flag on a Gaza resort hotel's roof. CNN geolocated the video to an area just over two miles from the Gaza-Israeli border.
"Soldiers of the 52 Battalion of the 401 Brigade are waving the Israeli flag in the heart of Gaza, by the beach," a soldier is heard saying in the video, taken several miles north of central Gaza City. "We will not forgive nor forget, and we’ll not stop until the victory."
The video is one of the first glimpses into where Israeli ground forces have been, and what they've been doing, during the expanded ground operations in Gaza.
A communications blackout in Gaza has significantly hampered the flow of information out of it, though providers said service was gradually being restored Sunday.
The video was published by Israeli newspaper Israel Hayom. CNN has asked the Israel Defense Forces for comment on the video, and why soldiers are installing an Israeli flag on the hotel roof.
On the ground: A CNN team in the Israeli city of Sderot, near the Gaza Strip perimeter, heard machine gun fire at regular intervals Sunday.
The gunfire was heard from the northern part of the enclave, close to the border, while the Israel Defense Forces continued to fire artillery rounds and mortars from outside the border further south.
Earlier on Sunday, IDF tanks and armored personnel vehicles were seen approaching the border while helicopters, drones and fighter jets flew overhead.
A large column of vehicles was seen north of the strip. Staging grounds further away from the border that were full of tanks and armored vehicles just a few days ago are now nearly empty, suggesting the troops have moved closer to the perimeter.
