A New Jersey man who stabbed renowned British-Indian author Sir Salman Rushdie multiple times on a New York lecture stage has been convicted of attempted murder and assault.

Hadi Matar, 27, now faces a sentence of more than 30 years in prison.

The attack in August 2022 left Sir Salman with severe injuries including damage to his liver, vision loss in one eye and a paralysed hand caused by nerve damage to his arm.

The jury's guilty verdict on Friday came after a two-week trial in Chautauqua County Court in western New York state, near the site of the attack.

The jury also found Matar guilty of assault for wounding the interviewer, Henry Reese, who was on stage with the author. Mr Reese suffered a minor head injury during the attack.

Matar's sentencing date has been scheduled for 23 April.

The attack took place more than 35 years after Sir Salman's novel, The Satanic Verses, was first published.

The novel, inspired by the life of the Muslim Prophet Muhammad, sparked outrage among some Muslims, who considered its content to be blasphemous. The book was banned in some countries when it was published in 1988.

Sir Salman faced countless death threats and was forced into hiding for nine years after Iran's religious leader issued a fatwa calling for the author's death due to the book.

But in recent years, the author said he believed the threats against him had diminished.

During the trial's closing arguments on Friday, prosecuting lawyer Jason Schmidt played a video in slow-motion of the attack, the Associated Press reports.

"I want you to look at the targeted nature of the attack," Mr Schmidt said in court, according to the news outlet. "There were a lot of people around that day but there was only one person who was targeted," he told the jury.

During the two-week trial, defence lawyer Andrew Brautigan argued that prosecutors had failed to prove Matar intended to kill Sir Salman. Matar had pleaded not guilty.

His lawyers declined to call any witnesses of their own and Matar did not testify in his defence.

Sir Salman, 77, testified that he was on stage at the historic Chautauqua Institute when he saw a man rushing towards him.

Recalling the incident, he said he was struck by the assailant's eyes, "which were dark and seemed very ferocious".

He initially thought he had been punched, before realising he had been stabbed - 15 times in total - with wounds to his eye, cheek, neck, chest, torso and thigh.
