The Turkish authorities have detained a man with a fake bomb trying to get into the office of Prime Minister Recep Tayyip Erdogan in central Ankara.
A security alert was raised when the man himself called the police to tip them off about a threat.
He was carrying an object made up to like an explosive device. Local media suggest the main components were putty, cling film and a piece of wire.
The man, who Turkey’s interior minister described as having “psychological problems”, was detained at the scene.
Shots were fired into the air by police, but no-one was injured.
Erdogan was not in the offices at the time.
