A group of Kurdish protesters entered the Tory campaign headquarters in London and, despite a large police presence, refused to leave.
Reportedly scores of activists entered the building shortly before 2pm on Tuesday afternoon and set up with flags inside the lobby.
The Metropolitan police blocked off the entrance to the building and, according to live video feeds from the scene, appeared to be trying to work with protest leaders to get them to leave.
Protesters against the Government's support of Turkey chanted "wake up UK" and "wake up Cameron".
At 4pm, protesters filed out of the building, decrying the Turkish government's "siege on Kurdish areas".
Calls to the Tory headquarters were not immediately answered.
