People have been evacuated and others "told to avoid windows" along a major road in Islington during a "security alert".
Emergency services closed part of Goswell Road, with TfL saying police are responding to a security alert near Angel Tube station.
A TfL spokesman added: "A1 Goswell Road is blocked between City Road and Wakley Street due to an emergency services incident."
People in the area took to Twitter to say they had been evacuated during the incident on Tuesday.

Another added: "Whats happening on Goswell Road in Islington? My auntie is at work and has been told to stay away from the windows."
A police spokesman said later confirmed cordons were in place "due to an unattended bag on a bus in Goswell Road".
"This security alert has now been cleared and is non-suspicious," he added.
