New York Police Commissioner William Bratton says the city is closely following developments overseas after Britain raised its terror threat level.

Bratton said Friday there is �no specific credible threat� to New York City. He says the NYPD is working with the FBI Joint Terrorism Task Force to monitor any developments.

The commissioner added that New York City�s �security posture� and NYPD resources are adjusted daily to conform to changing conditions around the globe.

Britain�s decision was related to developments in Iraq and Syria, but there was no information to suggest an attack was imminent.
