Obviously Israel is sending inferior cement to Gaza

From Ma'an:

The military wing of Hamas, al-Qassam Brigades, said Saturday that one of its members had been killed in a tunnel accident in the Gaza Strip.

In a statement, the group identified the dead man as Anwar Faraj al-Ghalban, 23, from Khan Younis. The statement did not specify how or where the accident took place.

Al-Qassam Brigades said in the statement that they would spare no effort in their resistance to Israel and would keep fighting to "free Palestine."

They said that their members were doing their best despite difficult circumstances to make preparations, including by digging tunnels, to fight the Israeli occupation.

Ma'an then pretends that most of the tunnel activity is for smuggling weapons from Egypt:

Smuggling tunnels that pass beneath the Egyptian border have served as a lifeline to the outside world for Gaza's 1.8 million inhabitants since Israel imposed a crippling siege on the coastal enclave in 2007, which is supported by Egypt.

A number of fighters in Gaza have been killed by accidents during military training exercises in recent years, and the tunnel networks, which are largely used for smuggling in the coastal enclave's south and military purposes in the north, are notoriously dangerous.

Hmmm, "military purposes in the north." What might those be?
