Rights group Amnesty International is urging Egypt to hold police and military members responsible for abuses against protesters and to reform those institutions to prevent future violations.

In one of two new reports Tuesday, the London-based group said its investigations showed protesters were killed, tortured and abused by Egyptian troops during demonstrations that took place under the country's former ruling military council.

It said protesters have been tried by military courts, but that soldiers responsible for the abuses have not been forced to face trials in independent, civilian courts.

The second report details abuses by the country's three main police forces, including beatings, arbitrary arrests and firing live ammunition into crowds.

Amnesty says Egypt needs “major reforms” to its police force in order to rebuild public trust. It also says a panel created by Egyptian President Mohamed Morsi to investigate the killing and injuring of protesters under military rule must be given time, resources and power to carry out its task.
