Terrorism charges filed against Manhattan truck attack suspect Sayfullo Saipov
What's the story
US prosecutors have charged 29-year-old Uzbek immigrant Sayfullo Saipov for killing at least eight people by mowing them down in a pickup truck in New York.
Saipov has also been accused of providing ISIS with material support and resources.
Police shot and injured Saipov at the scene of the attack, following which, he was treated in hospital.
Prosecutors said he spoke to them freely.
Statement
What did Saipov tell prosecutors?
According to federal court documents, Saipov said he planned the attack two months ago.
He said Halloween was intentionally chosen by him as the streets would be more crowded.
He wanted to display ISIS flags on his truck but felt it better not to attract attention to himself.
Investigators found 90 ISIS propaganda videos from his phone.
Saipov said the videos inspired him.
