Yasmeen Ali, 44, pleaded guilty to three charges of manslaughter at Bristol Crown Court, admitting the killings of Fares Bash, seven, Joury Bash, three, and nine-month-old Mohammed Bash. The children's bodies were discovered on Blaise Walk in Sea Mills, Bristol, on 18 February 2024.
An inquest was previously told the three children died of knife wounds, with injuries to their chests and necks. Fares Bash also showed possible signs of asphyxia.
The incident began with a three-minute call to 999 in which Ali, out of breath and speaking Arabic, told police she was "going to God". Officers who arrived found the children dead and Ali with self-inflicted wounds to her neck. The house was described as "dirty and chaotic".
Appearing through an interpreter in a purple coat and black headscarf, Ali wept as the children's fatal injuries were read out. Only six people were allowed into the courtroom to minimise the impact on her mental health, and her defence team told the court she suffered from "acute psychosis". The children's father, Alfil Bash, left the room as the details were read.
Avon and Somerset Police said Ali was detained under the Mental Health Act after being assessed by medical experts at the scene. She was later discharged from Southmead Hospital and now lives in a secure psychiatric hospital. The force referred itself to the Independent Office for Police Conduct because of prior contact with the family, but the watchdog said no investigation was required.
The children's father has previously spoken of his devastation, describing the children as "his whole world" and saying he "could not get his head around what had happened". Community vigils were held in the children's memory after their deaths.
Sian Randall, headteacher at Sea Mills Primary School, where the two eldest children were pupils, said there were "no words that display the depth of sorrow". "Fares was a ray of sunshine, with a mischievous smile and ray of spirit that touched everyone he encountered," she said. "Joury was a beacon of pure joy, her smile would light up a whole room. Their absence will always be felt."
