From JPost, 11 Aug 2012, by KHALED ABU TOAMEH:
For first time, Palestinian Authority publicly calls for destruction of underground tunnels, asking Egypt to destroy those along its border with Gaza to tighten blockade.
Buoyed by growing tensions between Hamas and Egypt in wake of last week's terror attack in Sinai, the Palestinian Authority Saturday called on the Egyptians to tighten the blockade on the Gaza Strip by destroying all underground tunnels along their shared border.
The PA said that the tunnels do not contribute to the economy in the Gaza Strip and are being used only by a small number of people for personal gain.
This was the first time that the PA had ever called publicly for the destruction of the underground tunnels along the border between the Gaza Strip and Egypt.
The appeal came as PA officials continued to insist that some of the terrorists who killed 16 Egyptian border guards had come from the Gaza Strip.
The officials are hoping that tough Egyptian security measures in Sinai, including the destruction of the tunnels, would undermine Hamas's rule in the Gaza Strip and possibly bring about its collapse.
In the past few days, senior officials in Ramallah have been working hard to convince the Egyptians that Hamas and other radical groups in the Gaza Strip were linked, in one way or another, to the terror attack.
The PA has also provided the Egyptian authorities with the names of several suspects from the Gaza Strip, a PA security source in Ramallah disclosed.
"We have good security ties with the Egyptians and we are trying to help them capture the terrorists," the source explained. "We have good reason to believe that terror groups from the Gaza Strip were involved in the attack. These groups operate under the looking eye of the Hamas government and sometimes even receive support from it."
The Sinai terror attack came at a time when PA leaders in the West Bank were beginning to express concern over improved relations between Cairo and Hamas in light of the election of Muslim Brotherhood candidate Mohamed Morsy as president.
Many Egyptians have held Hamas responsible for the terror attack, claiming that the terrorists had entered Sinai though underground tunnels that are under the strict supervision of the Hamas government.
Some Egyptians have urged their government to retaliate by destroying the tunnels and permanently closing the Rafah border crossing.
