CAIRO — A fire ripped through a packed church during morning services in Egypt’s capital on Sunday, killing at least 41 worshippers and injuring 14. The church quickly filled with thick black smoke, and witnesses said several trapped congregants jumped from upper floors to escape. “Suffocation, suffocation, all of them dead,” said a distraught witness, who only gave a partial name, Abu Bishoy. The cause of the blaze in the Abu Sefein church in the working-class neighborhood of Imbaba was not immediately known.
