Police departments overseeing major U.S. cities say they are constantly monitoring for any terror threats and are a little more alert now that the Islamist Taliban, allies of al Qaeda, have reconquered Afghanistan.

A spokesperson for Washington, D.C.’s, Metropolitan Police Department (MPD) told Fox News they are not aware of any credible threats to the city but urged the local community "to report any suspicious behavior to the proper authorities."

"MPD continues to monitor and assess information we gather regarding any potential threats to the city in collaboration with our local and federal partners to ensure the public’s safety," spokesperson Alaina Gertz said in an emailed statement. 

A representative for the Los Angeles Police Department said the agency has deployed additional officers in certain locations throughout the city and is working "closely" with federal partners related to any potential threats in their region. The LAPD has not identified any threats linked to the events in Afghanistan, according to an emailed statement. 

Reps for police departments in Miami and Austin said their agencies have not uncovered any specific threats in their jurisdictions. 

John Elder, a spokesperson for the Minneapolis Police Department, told Fox News officials "constantly monitor things that can be flash points locally, nationally and internationally."

He added: "We adjust our patrol tactics to address current events and possible threats."

The New York Police Department declined to comment.
