ALEXANDRIA, Egypt — Egyptian security officials said the police investigation into a church bombing that killed 21 people is focusing on a local group of Islamic hard-liners that is inspired by but not directly linked to al-Qaida.
The officials said police are also examining lists of air passengers who arrived recently in Egypt from Iraq, where the local al-Qaida branch has threatened Egyptian Christians.
The officials spoke Sunday on condition of anonymity because the investigation has not yet been completed.
