According to a statement from the Ministry of Interior, the twin brothers who brutally killed their mother and seriously wounded their father and brother were among the 81 criminals who were sentenced to death on Saturday.

As a result of their embrace of Daesh (so-called IS) ideology, the brothers committed the heinous crime in the firm belief that their "family had become infidels".

At dawn on May 24, 2016, Saudi Arabia woke up to horrific news: twin brothers had stabbed their brother and stabbed their mother in Al-Hamra, a crowded neighborhood in Riyadh.

After fleeing the scene of the murder, they were arrested by security authorities.

The statement noted that Saleh Bin Ibrahim Al-Oraini and Khalid Bin Ibrahim Al-Oraini were convicted of several crimes, including murdering their mother through trickery and deception, attempting to kill their father and brother, and adopting Daesh ideology.

They were sentenced to death after being convicted of a number of crimes, including the brutal murder of their mother and their embrace of Daesh ideology. In the end, the higher courts upheld the death penalty.

In Al Hamra, Khalid and Saleh stabbed their 67-year-old mother Haila, 73-year-old father Ibrahim Bin Ali Al-Oraini, and 22-year-old brother Suleiman. Both their father and brother suffered serious injuries, while their mother died of her wounds.

Mother objected to her sons joining Daesh terrorists in Syria, according to reports. The brothers lured their mother into one of their rooms of their house, where they killed her with the help of their brother.

Her second brother held her from behind, putting his left hand on her mouth to muffle her screams. In various places on her body, she was stabbed until she fell to the ground. The crime was premeditated as evidenced by the evidence.

The brothers said they committed the murder because they believed their "family had become infidels". In addition, they claim that their father "was an infidel" who attacked him with several blows to the head and hands.

They used a machete and knives recovered from the crime scene that they brought from outside. Having snatched a resident's car by force, they fled the scene. They were arrested in the town of Al-Dalam in the governorate of Al-Kharj after a massive manhunt.
