Two men suspected of planning an attack on a Manhattan synagogue were arrested by New York City police Wednesday night, a law enforcement source told CNN Thursday.
The men were arrested in a police sting as they attempted to purchase three or four guns and a grenade that they intended to use in an attack against a synagogue, according to the source.
The threat was "on the radar screen for a few months," long before the killing of al Qaeda mastermind Osama bin Laden in Pakistan, the source said.
The men, who are of North African descent, have not yet been publicly named, the source said. One is said to have an extensive criminal record, including drug and weapons charges.
