In response to the attack, officials from the Egyptian presidency announced a three-day mourning period.
The mosque is understood to have adherents who follow the Sufi interpretation of Islam whose follower have faced numerous attacks by Islamic State group militants who operate in the area.
Three police officers who spoke to Associated Press on the condition of anonymity said that men in off-road vehicles opened fire on worshippers inside the mosque during the sermon.
Ministry of Health spokesman Khaled Mujahid said the militants set off a bomb during the attack. His comments were published in the state-backed Al-Ahram newspaper.
