( dpa ) - Egypt sent more security forces to its border with the Gaza Strip Monday for fear that Palestinian militants may storm the border after Israel tightened its blockade of the territory, according to security officials. The Egyptian authorities received information that Palestinian militants may storm the Rafah crossing, which prompted them to send hundreds of security forces for additional deployment along the joint border with the Gaza Strip, the sources said. Palestinians had previously stormed the crossing through holes rammed in the high concrete wall that marks the border with Egypt. This development on the border comes as Israel tightens its blockade of the Gaza Strip, which has been enforced since the Islamic militant group Hamas took control of the territory seven months ago.
