Hundreds of Egyptians march from the Fath Mosque in Ramses to St. Mark's Coptic Cathedral in Abbasiya to protest against an attack at the Christian place of worship earlier in the week.
On Sunday 7 April, the cathedral held a funeral for four victims of sectarian fighting in El-Khosous, north of Cairo. Protesters at Tuesday's march said the funeral was attacked, and clashes soon ensued. Satellite TV footage shows police firing teargas towards the cathedral surrounded by civilians throwing rocks.
Marchers from both faiths said they rejected attempts to divide Muslim and Christians.
