Satellite imagery and videos from open and official sources suggest that Israeli ground forces are closing in on Gaza City, the largest and most densely packed population center in the Palestinian enclave. The Israel Defense Forces (IDF) claim that they have encircled the city from the air, land, and sea and are advancing in battles to destroy terrorist infrastructures and eliminate militants. The IDF's ground offensive into Gaza began a week ago, with troops pushing forward on three axes to divide the strip into two. The European Space Agency satellite imagery from Wednesday indicates that Israeli troops are less than a kilometer away from completely encircling Gaza City. Videos have shown Israeli forces moving in from the north and footage has also shown them on a highway seemingly blocking movement into Gaza City from the south. The urban area of Gaza City is home to nearly 2 million people living in a densely populated 88-square-mile area, which equates to about 21,000 people per square mile. As Israeli forces encircle Gaza City, the urban fight is likely to intensify with potential higher costs in casualties.
