Israel’s military has deepened its hold on the Gaza Strip, significantly expanding the territory it controls under the seven-month cease-fire and fortifying the line that separates it from areas controlled by Hamas.

Israel now holds around 59% of the enclave, up from 53% at the start of the U.S.-brokered cease-fire in October, people familiar with the matter said. The increase came as Israeli troops moved the so-called yellow line, which marks the division of territory, deeper into Hamas’s zone of control, the people said. In at least one spot, Israel moved the line forward a few hundred yards to intersect with Salah al-Din Road, Gaza’s main north-south artery.

In addition, in central Gaza, the Israeli military has been fortifying the line with a deep trench and high sand berms along its length, satellite images show. Similar earthworks can be seen in areas of northern and southern Gaza, but the fortifications through the center, where much of the population lives, are longer, more continuous and designed to be harder to breach since the area is more vulnerable to attack, Israel’s military says.

Satellite images show the line is now dotted with at least seven new outposts, each protected by sand berms. Some are paved with asphalt and host more than a dozen buildings. They beef up Israel’s position on the line and add to dozens of outposts scattered throughout its side of the enclave.
