CAIRO - A Cairo court ruled on Tuesday 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 that run Gaza, but many Egyptians fear the enclave is a security risk for Egypt. Leftist lawyers said they brought the case with activists to force the government's hand.

President Mohamed Morsi's national security adviser Essam Haddad has said Egypt will not tolerate the two-way flow of smuggled arms through the tunnels that is destabilizing its 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.
