At least three people died, including a child, and eight others were wounded when gunmen opened fire on people attending a Coptic Christian wedding outside a church on the outskirts of Cairo.

According to an Interior Ministry communique, the dead included an 8-year-old boy, a man and a woman.

An official with the security services told Efe that two masked men on a motorcycle opened fire indiscriminately on the people in front of the church of Our Lady on Uarak al Hadra, one of the islands in the Nile near Cairo.

After the incident, security forces were deployed to the site.

The Attorney General's Office ordered an investigation to find those responsible for the attack.

Four years ago the same church became known for an alleged appearance of the Virgin Mary, a circumstance that attracted thousands of Egypt's Christian faithful.

Christians represent 10 percent of the more than 80 million people in Egypt and complain that they are discriminated against in the heavily Muslim nation.

Attacks against Christian churches have increased in recent months after Islamist President Mohammed Morsi was deposed last July by the armed forces.

The pope of the Coptic Church, Theodoros II, was one of the figures who appeared on July 3 along with army chief Abdel Fatah al Sisi when the latter announced Morsi's ouster and the start of a new process of political transition. EFE
