Egyptian generals have defended the army's actions in cracking down on a Christian protest in Cairo that left 25 people dead.
The army has denied charges that troops used live ammunition or that army vehicles crushed demonstrators under their wheels.
In what was the worst violence since Hosni Mubarak was ousted, activists said armoured vehicles sped into a crowd on Sunday to disperse a protest over an attack on a church building in southern Egypt.
Christians turned their fury on the army. They said protesters responded with stones and other projectiles only after the military used heavy-handed tactics. Military and other vehicles were set on fire in the violence.
The violence drew criticism from Muslims and Christians alike.
The generals produced footage they said showed army vehicles avoiding demonstrators and called for unity between Christians and Muslims.
They also sought to pin the blame for inciting violence on "foreign elements".
Amnesty International said some of the dead had bullet wounds.
A doctor at a Coptic hospital had told reporters on Monday that 14 of the 17 dead brought in to his hospital had been hit by bullets. The doctor said three bodies were crushed.
Christians, who make up 10% of Egypt's roughly 80m people, had taken to the streets after accusing Muslim radicals of partially demolishing a church in Aswan province last week.
There has been a rise in violence against churches since the ousting of President Hosni Mubarak, who had repressed Islamist groups.
