NEW YORK - The suspect in New York City's deadliest terror attack since 9/11 was indicted Tuesday on murder and terror-related charges, said the U.S. Attorney's office for the Southern District of New York (SDNY).

A grand jury in the Southern District of New York returned a 22-count indictment against Sayfullo Saipov in connection with his alleged terrorist attack in lower Manhattan on Oct. 31, which killed eight people and injured 12 others.

Charges against the 29-year-old Uzbek native include eight counts of murder and 12 counts of attempted murder, both in aid of racketeering, and one count of providing and attempting to provide material support to the Islamic State (IS) group, among others.

"Like many terrorists before him, Saipov will now face justice in an American court. And like New York City's response to his alleged attack, we expect that justice in this case will be swift, firm, and resolute," said SDNY Acting U.S. Attorney Joon H. Kim in a press release.

According to the indictment, Saipov allegedly told authorities he was inspired to carry out the attack by IS videos he had watched on his phone.
