JERUSALEM - Police in Israel have arrested a man they believe threatened to bomb Jewish centers in the U.S. and around the world.

It's not clear if he targeted any sites in New York.

A Jewish community center on Staten Island was evacuated last month over a bomb threat.

The 19-year-old suspect, whose name has not been released, is Jewish and has dual American-Israeli citizenship.

They say he used hacking technology to hide his location while making the threats.

The suspect appeared in court Thursday, but covered his face as he walked past reporters.

Investigators say he was also responsible for a bomb scare at JFK Airport more than two years ago.

The Anti-Defamation League says there have been dozens of threats against Jewish centers and schools in recent weeks.
