Israeli forces have progressed miles since entering the Gaza Strip overnight on Oct. 27 and appear to have effectively severed Gaza City from the south, new satellite imagery shows. Vehicle tracks made over the past week and visible on Planet Labs images taken Nov. 3 show advances along three main routes, from the northwest, northeast and south. Although Israeli forces along the southern route have advanced all the way to the Mediterranean Sea, they appear not to have made significant progress along other routes in recent days, and videos have showed heavy fighting in some of those locations.
