Dozens Killed During Alleged Prison-Break Attempt in Egypt

CAIRO—Dozens of prisoners detained in recent clashes between Egypt’s interim authorities and antigovernment protesters were killed during an attempted prison break on Sunday, according to Egypt’s interior ministry, adding to a death toll from the past week that had already surpassed 800.

At least 36 prisoners were killed when they attempted to escape from a prison transport vehicle that was ferrying them from a pre-detention facility to the large Abu Zaabal penitentiary, Egypt’s state-run television station reported.

The prisoners were among a group of more than 600 supporters of ousted President Mohammed Morsi who had been arrested during continuing clashes over the past four days, said Gen. Hani Abdullatif, an interior minister spokesman.
