ISIS claims New York truck attacker is 'caliphate soldier'
Sayfullo Saipov allegedly told investigators he was inspired by watching ISIS propaganda videos
ISIS has claimed responsibility, without providing proof, for a truck attack earlier this week that killed eight people in the deadliest assault on New York City since Sept. 11, 2001.
The militant group on Thursday described accused attacker Sayfullo Saipov, 29, as "one of the caliphate soldiers" in a weekly issue of its al-Naba newspaper.
The Uzbek immigrant was charged in federal court on Wednesday with acting in support of Islamic State in Iraq and Syria by plowing a rented pickup truck down a popular riverside bike trail, crushing pedestrians and cyclists and injuring a dozen people in addition to those killed.
According to the criminal complaint against him, Saipov told investigators he was inspired by watching ISIS propaganda videos on his cellphone, felt good about what he had done, and asked for permission to display the group's flag in his room at Bellevue Hospital.
Saipov was taken to Bellevue after being shot in the abdomen by a police officer before his arrest.
Trump claims military response
U.S. President Donald Trump, who has called for Saipov to receive the death penalty, said in a Twitter post on Friday that ISIS had claimed as their soldier the "Degenerate Animal" who killed and wounded "the wonderful people on the West Side" of Lower Manhattan.
"Based on that, the Military has hit ISIS 'much harder' over the last two days. They will pay a big price for every attack on us!" Trump tweeted.
Earlier this week, Trump suggested sending Saipov to the Guantanamo Bay military prison in Cuba, where terrorism suspects apprehended overseas are incarcerated. But on Thursday, he said doing so would be too complicated.
The U.S. president has also urged Congress to end the diversity immigrant visa program under which Saipov entered the United States in 2010.
The diversity program, signed into law in 1990 by Republican president George H.W. Bush, was designed to provide more permanent resident visas to people from countries with low U.S. immigration rates.
Five Argentine tourists, a Belgian woman, a New Yorker and a New Jersey man were killed in Tuesday afternoon's attack.
Prospect of death penalty
The attack unfolded just blocks from the site of the World Trade Center, where some 2,600 people were killed when suicide hijackers crashed two jetliners into the Twin Towers 16 years ago.
One of the two criminal counts Saipov faces, violence and destruction of motor vehicles causing the deaths of eight people, carries the death penalty if the government chooses to seek it, prosecutors said.
Saipov waived his right to remain silent or have an attorney present when he agreed to speak to investigators from his hospital bed, the criminal complaint said.
The Federal Bureau of Investigation has said it has located another Uzbek man, Mukhammadzoir Kadirov, 32, who it said was wanted for questioning as a person of interest in the attack.
Citing an unnamed law enforcement official, ABC News reported on Friday that Saipov placed a telephone call to Kadirov immediately before he carried out the attack. ABC News said the significance of the call was not known.
