Egyptian prosecutors have opened an investigation into the Monday morning deadly attack on a liquor store in Giza's Omraneya neighborhood, which left two killed.
According to initial police investigations, a masked gunman driving a Tuk Tuk opened fire on the liquor store killing the brothers Ashraf Boules Azer and Adel Boules Azer, before fleeing the scence.
It is not yet clear whether the brothers owned or worked at the store.
The motive for the attack, which took place on New Year's eve, the busiest night of the year for liquor stores, also remains unclear.
Ashraf died at the scene, while Adel died of his injuries at Om Al-Masryeen Hosptial in Giza.
Police detectives have been interviewing witnesses, examining surveillance cameras on nearby buildings and along the escape route in an effort to identify the suspects and establish the facts of the incident.
Liquor stores in Egypt are typically owned by Christians. The stores and their owners have been the target of various attacks in the past.
