A paranoid schizophrenic who broke into his friend's house, chased him down the street and then stabbed him to death told police he was "Allah's assassin".
Ahmed Noor, who is originally from Somalia but who was living at Agincourt Avenue in south Belfast when he attacked his friend, also said it was the "happiest day of my life" after he "killed the king".
The 34-year-old pleaded guilty to the manslaughter of Mohsin Bhatti, who at the time of his death was a 29-year-old asylum seeker from Pakistan living on India Street in Belfast. The plea was accepted on the grounds of diminished responsibility.
Belfast Crown Court heard yesterday that Mr Bhatti called 999 from his mobile at 5am on January 29 last year, asking for police before the line went clear.
He was then heard to scream, with the Crown saying this call to the emergency services was a "graphic indicator of the fear, distress and horror of the attack".
Noor repeatedly stabbed Mr Bhatti with two knives, resulting in multiple wounds.
The injuries included fatal stab wounds to his chest, penetrating his heart, and a gaping wound to his abdomen.
Telling Madam Justice McBride that Noor's attack was "barbaric", Crown barrister Ciaran Murphy QC said that when the police arrived at the scene, they found Noor beside his victim, covered in blood.
Noor told how during the attack he spat on and stood on Mr Bhatti's face and said: "I will get rid of all suicide bombers - they're not real Muslims".
Mr Murphy branded the attack on Mr Bhatti as "unprovoked" and said it was carried out when Noor was "under the self-induced influence of drugs."
The defendant, described in court as a paranoid schizophrenic with a "cannabis dependence syndrome", was remanded in a secure unit at Knockbracken Healthcare Park in Belfast.
His barrister, Frank O'Donoghoe QC, said that his client had a long-standing addiction to cannabis, adding that when he killed his friend he was "in a psychotic state and had taken drugs".
He told the court that Noor apologised for his conduct last January, which occurred "at a time when clearly his mental illness substantially impaired his mental reasoning".
Madam Justice McBride said that she would pass sentence next Thursday.
