US authorities have arrested a man described as a supporter of so-called Islamic State (IS) and accused him of planning an attack in New York State.

Emanuel Lutchman, 25, from Rochester, was charged on plotting to kill people at a restaurant on New Year's Eve.

Mr Lutchman told an FBI informant he would use a machete and knifes in the attack, officials say.

Before his arrest, he made a video pledging allegiance to IS leader Abu Bakr al-Baghdadi, the FBI said.

Mr Lutchman came to the attention of authorities after he began expressing support for IS online.

"I will take a life, I don't have a problem with that," Mr Lutchman is quoting as saying in court documents.
