A black flag with white Arabic writing, similar to those flown by jihadist groups, was flying at the entrance of an east London housing state near Canary Wharf.
In a highly provocative gesture, the emblem was planted on top of the gates of the Will Crooks estate on Poplar High Street, and is surrounded by flags of Palestine and slogans.
The flag bears similar writing to the jihadi flags that have been flown by the extremist group in Iraq and other jihadi groups since the 1990s. When the estate was approached last night, a group of about 20 Asian youths swore at Guardian journalists and told them to leave the area immediately. One youth threatened to smash a camera.
