Shocking images have emerged appearing to show the moment the Turkish Prime Minister Recep Tayyip Erdogan's adviser, Yusuf Yerkel, kicked a protester being restrained on the ground during anti-government demonstrations following an explosion in a coal mine that left 282 dead and scores injured.
The photos were taken in Soma, the town where the mine collapsed after the explosion on Tuesday.
It said witnesses at the scene claimed the person being restrained by parliamentary police in the image was in fact a relative of one of the dead miners.
The photos caused outrage after they were shared across social media thousands of times and Turkish newspapers Cumhuriyet, Milliyet and others on Thursday printed photographs they said were of an Erdogan aide kicking a protester.
Yerkel confirmed in a telephone conversation that he was the man seen about to kick a protester and said he would release a statement.
Yerkel is listed as a former student of London's SOAS university.
The incident came as hopes faded for the 150 miners still trapped in the town of Soma.
Erdogan was heckled as he visited the town and spoke during a news conference, where he defended Turkey’s mining safety record by saying: "These are ordinary things. There is a thing in literature called `work accident'... It happens in other work places, too."
Protesters shouted "murderer!" and "thief!" and Mr Erdogan was forced to seek refuge in a supermarket, surrounded by police. Demonstrations took place across Turkey.
In Turkey’s capital Ankara police fired water cannons and tear gas at 800 protesters marching to the Energy Ministers office and the town’s ruling party offices were also attacked.
President Abdullah Gul visited the scene and offered his condolences to the family of the miners, where he described the events in Soma as a "huge disaster". "The pain is felt by us all," he added.
Rescue operations were brought to a halt for several hours on Thursday morning to allow high concentrations of gas underground to be cleared. Officials said 363 miners had been evacuated, but no survivors have been brought out since Wednesday morning. There were 787 people inside the mine at the time of the explosion, approximately four miles from the entrance and two miles underground.
Energy Minister Taner Yildiz told reporters that rescue efforts are now focusing on two areas inside the mine where a blaze is still raging and hindering the operation.
