CAIRO - Egypt's chief prosecutor says in a statement that the attack on a Sinai mosque has killed 305 people, including 27 children.

  

In a statement Saturday, Nabil Sadeq says the attack a day earlier also left 128 people wounded.

  

Sadeq says it was carried out by 25-30 militants who arrived at the mosque in the small town of Bir al-Abd in five all-terrain vehicles. He says the militants stationed themselves at the mosque's main door and 12 windows before opening fire on worshippers inside. They also torched seven cars belonging to the worshippers that were parked outside.

  

There was no claim of responsibility for the attack, the deadliest by Islamic extremists in Egypt's modern history. The mosque is frequented by Sufi Muslims, a mystic school of Islam that militants consider heretic.
