Waterville's massacre killed at least 9 people and injured 32, the health ministry said on Wednesday.
Israel has called on Egyptian President Abdel Fattah al-Sisi to visit Israel to denounce its actions.
In his first official visit to Egypt last week, President Sisi visited the scene of the massacres and left no doubt in his voice that he regrets the fate of the mourners and will do whatever it takes to prevent such an event from happening again.
It is the first major international trip for Egypt, which the new government is now seeking to distance itself from its Muslim Brotherhood-led military government and emphasise the Arab goals of democracy and opposition to Israel.
