Three children died after being stabbed to the chest and neck in an incident in Bristol, an inquest revealed.
Fares Bash, 7, Joury Bash, 3, and Mohammed Bash, 9 months, died of stab wounds at their home in the Sea Mills area of the city on February 18.
An inquest into their deaths was opened at Avon Coroner’s Court on Tuesday.
The court heard the three children died from stab wounds and injuries to their chest and neck.
Feres Bash also showed signs of possible suffocation.
Coroner Dr Peter Harolin adjourned the inquest while detectives continued their investigation.
He said: “As the police investigation is still ongoing, I will postpone the trial pending the outcome.”
The children’s father, Alfil Bash, attended the opening of the inquest.
Outside the hearing, he cried as he spoke of his grief at losing his child and said he could not understand what had happened.
Mr Bash described his eldest son as a “genius boy” who loved football, singing and maths.
In late February, hundreds of people attended a vigil in memory of the three children.
Avon and Somerset Police said earlier this month that a 42-year-old woman had been arrested on suspicion of murder.
She was taken to hospital with non-life-threatening injuries and was detained under the Mental Health Act.
Following the incident, Avon and Somerset Police reported it to the Independent Office for Police Conduct (IOPC) with prior contact, but the watchdog said an investigation was not required.
