San Francisco Frontiers - Salman Rushdie in surgery after being stabbed onstage

Police said a male suspect stormed the stage and attacked Rushdie and an interviewer, with the writer suffering "an apparent stab wound to the neck."

Rushdie was rushed by helicopter to hospital and taken into surgery, his agent Andrew Wylie said in a statement on Twitter, pledging to provide an update on his condition as soon as possible.

Social media footage showed people administrating emergency medical care onstage immediately after the attack. The interviewer also suffered a head injury.

A suspect was taken into custody by state police, who gave no immediate details about his identity or probable motive.

The attack occurred as Rushdie was about to give a speech at the Chautauqua Institution, which holds arts programs in a tranquil lakeside community 70 miles (110 kilometers) south of Buffalo city.

New York governor Kathy Hochul condemned the stabbing and hailed Rushdie as "an individual who has spent decades speaking truth to power."

"We condemn all violence, and we want people to be able to feel (the) freedom to speak and to write truth," she said.

- A decade in hiding -

Rushdie, 75, was propelled into the spotlight with his second novel "Midnight's Children" in 1981, which won international praise and Britain's prestigious Booker Prize for its portrayal of post-independence India.

But his 1988 book "The Satanic Verses" brought attention beyond his imagination when it sparked a fatwa, or religious decree, calling for his death by Iranian revolutionary leader Ayatollah Ruhollah Khomeini.

The novel was considered by some Muslims as disrespectful of the Prophet Mohammed.

Rushdie, who was born in India to non-practicing Muslims and today identifies as an atheist, was forced to go underground as a bounty was put on his head -- which remains today.

He was granted police protection by the government in Britain, where he was at school and where he made his home, following the murder or attempted murder of his translators and publishers.

He spent nearly a decade in hiding, moving houses repeatedly and being unable to tell his children where he lived.

Rushdie only began to emerge from his life on the run in the late 1990s after Iran in 1998 said it would not support his assassination.

Now living in New York, he is an advocate of freedom of speech, notably launching a strong defense of French satirical magazine Charlie Hebdo after its staff were gunned down by Islamists in Paris in 2015.

The magazine had published drawings of Mohammed that drew furious reactions from Muslims worldwide.

- An 'essential voice' -

Threats and boycotts continue against literary events that Rushdie attends, and his knighthood in 2007 sparked protests in Iran and Pakistan, where a government minister said the honor justified suicide bombings.

The fatwa failed to stifle Rushdie's writing and inspired his memoir "Joseph Anton," named after his alias while in hiding and written in the third person.

"Midnight's Children" -- which runs to more than 600 pages -- has been adapted for the stage and silver screen, and his books have been translated into more than 40 languages.

Suzanne Nossel, head of the PEN America organization, said the free speech advocacy group was "reeling from shock and horror."

"Our thoughts and passions now lie with our dauntless Salman, wishing him a full and speedy recovery. We hope and believe fervently that his essential voice cannot and will not be silenced."

Chuck Schumer, a senator representing New York, called the assault "an attack on freedom of speech and thought, which are two bedrock values of our country."

"I hope Mr. Rushdie quickly and fully recovers and the perpetrator experiences full accountability and justice," he said.
