As news continues to break on the suspected terrorist attack on the Rainbow Bridge connecting the U.S. and Canada at Niagara Falls, we're learning that a CBS News report from Tuesday evening reported on "growing concerns about security" in New York state "with the escalating violence in Gaza." 

CBS News' Catherine Herridge reported:

"CBS News has obtained a security alert suggesting an increasing terrorist threat to New York state. The New York state intelligence bulletin points to Israeli operations against Hamas, and specifically that increase in civilian casualties, raises the likelihood that violent extremist threat actors will seek to conduct attacks against targets in the West, with New York state being a focus."

Herridge also reported that likely targets included protests and other public events. As a result of the increased threat alert, security increased around synagogues and extra police were brought in for the Macy's Thanksgiving Day parade, although there was believed to be no "credible threat."
