On Saturday, militants dressed in Israeli army uniforms sneaked across the border and killed two Israeli soldiers, which as The Wall Street Journal notes, was “the worst blow to the Israeli military on its side of the Gaza border in years.”
The underground channels provide Hamas with a significant advantage, as Israel fears they can be used to infiltrate Israel and ambush civilians or soldiers.
According to NBC, the tunnels can be incredibly sophisticated. “Some boast concrete walls and ceilings, electric lighting, radio communications, sub-tunnels running off to the sides, and many are replete with booby-traps in case Israeli forces enter them.”
The Palestinian militant group has been expanding its network of tunnels for years. As one Israeli military official told The New York Times, “Actually there are two Gazas … One above ground and another under the ground.”
The tunnels made headlines in 2006 when Hamas used one to cross the border and seize an Israeli soldier. They held that soldier for five years before he was released in exchange for 1,000 jailed Palestinians. (Via Al Jazeera, Israel Defense Forces / CC BY SA 2.0)

Vox reports Gaza residents often suffer the most from the closure of these tunnels. “Civilians have a hard time accessing basic supplies, like medicines and construction material. The Gaza economy is stifled, and unemployment is estimated to be over 40 percent. The tunnels are the means Gazan civilians have to deal with it. Between Israel and Egypt, they may be in rough shape.”
Meanwhile, Israel has expanded its ground offensive. A hospital spokesperson in Gaza told CNN an Israeli shelling of the town near Gaza City on Sunday killed at least 40 people and wounded 300 others.
