Authorities in New York and Washington are on high alert after U.S. airstrikes on three Iranian nuclear sites on Saturday night. 

The NYPD mentioned on X that they’re keeping an eye on the ongoing developments in Iran. To be extra safe, they are sending more officers to protect religious, cultural, and diplomatic locations in NYC and are working together with federal agencies. They will keep watching for any effects these events might have on the city.

Shortly thereafter, the Metropolitan Police Department released a similar statement on the social media platform.

Sometimes, they place what is known as a ‘house of worship car’—a clearly marked police vehicle—right in front of a site.

More than anything, Mauro said, the authorities are monitoring online chatter from potentially dangerous bad actors.

He noted that they will be paying close attention online, keeping track of various online activities. The NYPD has a strong cyber counterterrorism team in place and will be intensively focused on this area.

Mauro said that local authorities in Washington will do the same, and also that Customs and Border Protection (CBP) will be keeping a close eye on who is entering the country. 

“You’re also going to be looking closely at things coming into the country, to the extent that you can, like at the border, at the airports … CBP is going to be on high alert.”
