New York truck attack suspect 'spent an entire year planning'
The main suspect in the New York truck rampage that killed eight people on Tuesday has told investigators he began planning the attack a year ago.
Sayfullo Saipov, 29, said he intended to kill as many people as possible and "felt good" about the Halloween attack.
The Uzbek immigrant, who faces federal terrorism charges, says he was inspired by so-called Islamic State. He was shot and injured by police at the scene.
Prosecutors say Mr Saipov spoke freely to them, waiving his right to avoid self-incrimination while in custody.
According to federal court papers, he said:
The attack was a year in the planning and he carried out a trial run with a rental truck last month
He intentionally chose Halloween because he believed there would be more people in the streets
He originally planned to target the Brooklyn Bridge as well
He wanted to display Islamic State (IS) flags on the truck, but decided not to draw attention to himself
He was inspired by 90 graphic and violent propaganda videos found on his phone - in particular, one in which IS leader Abu Bakr al-Baghdadi asks what Muslims are doing to avenge deaths in Iraq.
He arrived in America from Uzbekistan in 2010 and is a legal resident of the country.
CBS News quotes an intelligence source as saying he was known to US authorities after his name was associated with the subjects of FBI counter-terrorism investigations in 2015.
The source says he had some contact with individuals who were considered radicalised extremists, at least one of whom was Uzbek. It is unclear whether those being investigated were in the US or overseas.
