The Pope of Alexandria and Patriarch of the Saint Mark Episcopate Tawadros II held New Year's mass at the Two Saints Church in Alexandria, without prior notice, to mark the second anniversary of the bombing on New Year's Eve 2010.
In his sermon, the pope advised the congregation to repent from their sins and start the new year with prayers and good deeds.
Outside the church where 24 people were killed and more than 100 wounded, Muslims and the Christians held a vigil. They said security and executive authorities are intentionally delaying investigations into the incident.
They tied a large Egyptian flag linking the church with the mosque across the street, and placed pictures of the victims and lit candles.
Police are still investigating the incident.
