Egyptian attorney Wael Hamdy: "I filed the case because I was worried about the state of national security in my country after the rise of the Muslim Brotherhood to power and its unclear policies and links with Hamas."
A Cairo court ruled on Tuesday that the government must destroy all tunnels between Egypt and the Gaza Strip, removing a route for smuggled weapons but also a lifeline for Palestinians.
Egypt's ruling Muslim Brotherhood has close ties with the Hamas Islamists who run the Gaza Strip, but many Egyptians fear the enclave is a security risk for Egypt.
Egyptian President Mohammed Morsi's national security adviser Essam Haddad said Egypt would not tolerate the two-way flow of smuggled arms through the tunnels, which is destabilizing Egypt's Sinai Peninsula.
Egyptian forces flooded some of the tunnels earlier this month.
"The court ruled to make it obligatory that the government destroys the tunnels between Egypt and the Gaza Strip," Judge Farid Tanaghou said.
An estimated 30 percent of goods that reach Gaza's 1.7 million Palestinian residents come through the tunnels, circumventing a blockade imposed by Israel and Egypt for more than seven years.
