US man allegedly planned IS-inspired attack Ohio synagogue

US authorities on Monday charged an Ohio man with providing material support to the Islamic State for an alleged plan to carry out a mass shooting attack at a synagogue.

Damon Joseph, 21, allegedly had made a detailed plan to kill worshippers at a synagogue in the city of Toledo during the Jewish Sabbath, which begins at sunset Friday and lasts until nightfall Saturday.

He was arrested Friday when he picked up two semi-automatic assault rifles from a federal undercover agent. Police said the rifles had been rendered inoperable.

An affidavit filed in federal court claimed Joseph was inspired by Islamic State online propaganda and the October shooting at a Pittsburgh synagogue -- the worst anti-Semitic attack in modern US history in which 11 were killed.

"I admire what the guy did with the (Pittsburgh) shooting actually," Joseph wrote to an undercover agent, according to the affidavit.

"I can see myself carrying out this type of operation inshallah," he was quoted as saying, using a common Arabic-language expression which roughly translates to "God willing."
