US prosecutors on Wednesday announced federal terrorism charges against 29-year-old Uzbek immigrant Sayfullo Saipov, one day after he was arrested for a New York attack that killed eight people.

Prosecutors released a signed charging document that listed two counts:  provision of material support and resources to a designated foreign terrorist organization, and violence and destruction of motor vehicles.

Acting US Manhattan attorney Joon Kim was scheduled to announce the charges at a 5:45 pm (2145 GMT) news conference
