Islamic Hamas movement on Sunday deployed more forces along the Gaza Strip\'s southern borders with Egypt to tighten security with the neighboring country that is witnessing mass anti-president protests. The troops were deployed to prevent any illegal smuggling or crossing of elements from both sides of the borders, said Tareq Abu Hashem, the head of the National Security Forces in southern Gaza. He added that the deployment comes to refute accusations of Egyptian media report that Hamas, which controls the Gaza Strip, sent militants to fight on the side of President Mohamed Morsi, whose Muslim Brotherhood group is the historic mother of Hamas. A network of smuggling tunnels lies underneath the border between Gaza and Egypt which Hamas says is used to bring in materials and goods that Israel bans their entry.
