A 19-year-old man, who holds dual US-Israeli citizenship, has been indicted for hate crimes connected to threats against Jewish community centers, as well as threatening the Israeli embassy and cyberstalking, the US Justice Department said on Wednesday. Michael Kadar was arrested in Israel last year and is awaiting trial there. According to Reuters, US and Israeli authorities have previously charged him with making thousands of threats, including to airports, schools and Jewish centers, in the United States in 2016 and early 2017. Kadar was indicted by grand juries in Florida, Georgia and the District of Columbia for making threats from January to March 2017, the Justice Department said in a statement. The statement did not say whether he would be extradited to the United States. Kadar is alleged to have telephoned the Anti-Defamation League with a bomb threat and making a bomb threat in an email to the Israeli embassy in Washington, both in March 2017, the Justice Department said. Kadar, who is Jewish, was indicted for allegedly calling police in January 2017 about a hoax hostage situation at a home in Athens, Georgia, which included a threat to kill responding officers. Kadar also faces a federal cyberstalking indictment in Georgia. In Florida, Kadar was charged with making multiple threatening calls about bomb threats and gun attacks against Jewish community centers throughout the state in January and February 2017. He also is alleged to have made bomb threats against the Orlando International Airport and a school. According to Reuters, Kadars parents have said he has a brain tumor that caused autism and other mental problems, making him unable to understand the nature of his actions. If convicted, Kadar faces up to 20 years in prison for each hate crime charge and a maximum of 10 years for each bomb threat charge. The interstate threats charge, the hoax charge and cyberstalking charge call for up to five years in prison apiece.
