New York City man was sentenced to 18 years in prison on Tuesday after he pleaded guilty to charges of conspiring to aid ISIS and assaulting a federal law enforcement officer. Munther Omar Saleh, 22, was sentenced by US District Judge Margo Brodie in Brooklyn, according to John Marzulli, a spokesman for federal prosecutors. “Mr. Saleh is sincerely remorseful,” said Saleh’s lawyer, Deborah Colson, Reuters reported. “He is relieved to have put this behind him and he is ready to make amends,” she added. Saleh, a resident of the New York City borough of Queens and a US citizen, pleaded guilty in February 2017. He admitted that in 2015 he helped New Jersey resident Nader Saadeh with his travel and accompanied him to John F. Kennedy International Airport for a flight to Jordan, where Saadeh was subsequently detained, according to Reuters. Saadeh has pleaded guilty to charges of conspiring to help ISIS but has yet to be sentenced.
