CAIRO (Reuters) - A blast in front of a Christian church in Alexandria, Egypt on Sunday has injured several people, state news reported. The explosion comes just hours after a bombing rocked a Coptic church in Egypt's Nile Delta, killing at least 25 people and injuring 60. There was no immediate claim of responsibility for either blast and their causes remain unknown. (Reporting by Ahmed Tolba; Writing by Eric Knecht; Editing by Larry King)
