A Giza criminal court referred to Egypt’s Grand Mufti on Sunday death sentences handed to two Egyptians convicted of murder.

The two were convicted of killing two people including a policeman in 2015.

According to Egyptian law, all death sentences must be reviewed by the country's Grand Mufti—the highest Muslim religious authority—though his recommendation to the court is not legally binding.

The sentence must also be ratified by President Abdel-Fattah El-Sisi before being implemented. 

Last month, an Egyptian court upheld a death sentence for Adel Habara, a Sinai-based Islamist militant convicted of killing a police detective in Sharqiya governorate in 2012. Habara was executed three days later.
