Salman Rushdie has lost sight in one eye and the use of one hand after the attack he suffered while preparing to deliver a lecture in New York state two months ago, his agent has confirmed, according to a news report.

The 75-year-old author, who received death threats from Iran in the 1980s after his novel The Satanic Verses was published, was stabbed in the neck and torso as he came on stage to give a talk on artistic freedom at the Chautauqua Institution on 12 August.

Until now, the full extent of Rushdie’s injuries had been unclear. But in an interview with a foreign media, Andrew Wylie explained how serious and life-changing the attack had been.

“[His wounds] were profound, but he’s [also] lost the sight of one eye,” said Wylie. “He had three serious wounds in his neck. One hand is incapacitated because the nerves in his arm were cut. And he has about 15 more wounds in his chest and torso. So, it was a brutal attack.”

The agent declined to say whether Rushdie was still in hospital, saying the most important thing was that the writer was going to live.

Wylie also said he and Rushdie had talked about the possibility of such an attack in the past. “The principal danger that he faced so many years after the fatwa was imposed is from a random person coming out of nowhere and attacking [him],” he said.

“So, you can’t protect against that because it’s totally unexpected and illogical. It was like John Lennon[’s murder].

Two weeks before the attack, Rushdie had told an interviewer that he felt his life was “very normal again” and that fears of an attack were a thing of the past.
