Public figures, politicians and celebrities responded to the deadly attack in New York City on Tuesday that left eight people dead and 11 more injured.

As BBC reported, the driver, Sayfullo Saipov, who was 29 and an immigrant from Uzbekistan, was shot by police and survived. "Police say the suspect is currently being treated at Bellevue hospital, where he has been interviewed by officers," the BBC said.

New York Gov. Andrew Cuomo said officials found a note inside the truck he used in the attack that referred to the Islamic State group, according to CBS, which cited sources saying the suspect yelled "Allahu Akbar" — Arabic for "God is great" — when he exited a rented pickup truck that he used to strike pedestrians along Manhattan's West Side Highway.

Authorities plan to investigate whom the suspect has been talking to and his electronic devices for more information on who else may be connected to the attack.

"On its face, this of course has the hallmarks of a type of attack ISIS and al-Qaida have called and that cities all across the globe have tried to guard against," said Jeff Pegues, CBS News' justice and homeland security correspondent.

According to Fox News, Saipov reportedly entered the country through the Diversity Visa Program, which offers a lottery to people from countries without a lot of immigrants into the U.S.

President Donald Trump responded to the incident on Twitter, saying he hopes the Department of Homeland Security increases its vetting process.

First lady Melania Trump said her “heart breaks” for New York City.

Trump’s 2016 presidential election opponent Hillary Clinton responded to the news by saying New Yorkers are resilient.

Former President Barack Obama also praised New York City residents.

Former Vice President Joe Biden acknowledged first responders in his tweet.

Other U.S. politicians tweeted their thoughts and prayers.

International leaders, including Canadian Prime Minister Justin Trudeau and French President Emmanuel Macron, tweeted their thoughts for the U.S.

Current and former Broadway performers also tweeted about their heartbreak for NYC.

Music artists Sam Smith and Imagine Dragons similarly said their hearts have broken for New York City and its people.
