Every night in the run-up to Christmas thousands of Egypt's Coptic Christians have been gathering in a Cairo suburb eager for a glimpse of a vision that has given hope to their marginalised community.
It is three hours past midnight in Al-Warrak, a poor working class neighbourhood of the Egyptian capital, and a 10,000-strong crowd is silently staring at the sky.
Then the appearance of a mysterious light over the church tower jolts the gathering into a frenzy of cries and ululations. It is the apparition of the Virgin Mary, they say.
Thousands have been coming nightly since the first sighting of the Virgin Mary on December 10, in the hope of being blessed by her light.
The prospect of benediction is a much needed morale boost for the Christian minority which complains of systematic discrimination and marginalisation in the Muslim majority Arab country.
Tea vendors and sweet sellers snake through the crowd where thousands of families have gathered with young children and babies.
"The first person to spot the sighting of the Virgin Mary was a Muslim neighour. He took a video and pictures and distributed them to everyone," said Father Fishay, a priest at the Warrak church, describing how he first heard of the apparition.
Hassan, the Muslim neighbour, was sitting at his local coffee shop when at around 8:30 pm, he saw a strong light coming from the church.
