From the Daily News Egypt:

Egypt intends to bring to an end the weeklong freedom of movement between Gaza and Rafah in after Palestinians broke through the border wall, Foreign Minister Ahmad Aboul Gheit said Sunday.
“Egypt will take necessary actions and measures to control the border in Gaza soon,” the foreign minister said on Sunday after meeting with Palestinian Prime Minister Salam Fayyad in Cairo.
To this end, Egyptian forces tightened the security cordon around Rafah and prevented cars from entering and leaving. However, pedestrians from Gaza were still allowed to cross in and out of Egypt.
