(AP) — Hundreds of Egyptians held protests Saturday outside a Cairo courthouse and in the port city of Alexandria to demand answers over who was behind a bombing outside a church a year ago that killed 21 worshippers.

The attack in Alexandria took place Jan. 1, 2011, striking worshippers leaving a New Year’s Eve Mass.

A year later, no suspects are in custody. About 40 people were arrested within days of the attack but were released after Hosni Mubarak’s ouster because confessions from some of them were obtained under duress and none were found to have any link to the attack.
