(CNN) Iraqi social media star and model Tara Fares has been shot dead in Baghdad, security officials confirmed to CNN.

The death of Fares and other recent killings prompted Prime Minister Haider al-Abadi to order an investigation on Friday.

The former Miss Baghdad, and first runner-up for Miss Iraq, was killed on Thursday after gunmen opened fire on her in the capital's Camp Sarah neighborhood, according to a statement by Iraq's Interior Ministry, which is investigating the incident.

Ministry spokesman Maj. Gen. Saad Maan told an Iraqi TV station that two motorcyclists shot Fares while she was inside a vehicle.

The 22-year-old, a Christian whose father was Iraqi and mother Lebanese, was living in Erbil, but visited the capital occasionally. She was famous for her bold clothing and posts on social media.
