Turkey's Justice Ministry sends US dossier amid calls to extradite suspected coup plotter Fethullah Gulen

Turkey's Justice Ministry has sent a dossier to the US following President Recep Tayyip Erdogan's call for Washington to extradite the man he believes helped stage Turkey's failed coup attempt.

Prime Minister Binali Yildirim did not say whether the dossier amounted to an official extradition request.

However, he pledged to supply US authorities with evidence linking the coup attempt to Fethullah Gulen, a cleric and former Erdogan ally who is currently exiled in Pennsylvania.

Justice Minister Bekir Bozdag told reporters outside parliament: "We have more than enough evidence, more than you could ask for, on Gulen.

"There is no need to prove the coup attempt - all evidence shows that the coup attempt was organised on his will and orders."

Mr Erdogan has accused Gulen of being responsible for the coup, which has led to at least 265 deaths.

Addressing a crowd of supporters in Istanbul on Saturday, Mr Erdogan said: "I call on the United States and President Barack Obama: Dear Mr. President, I told you this before, either arrest Fethullah Gulen or return him to Turkey. You didn't listen."

The Turkish president has vowed to exact revenge after the coup attempt.

In the aftermath of the failed putsch, the Turkish government has embarked on a purge of suspected opponents, arresting around 6,000 people and suspending almost 8,000 police officers.

Some 257 staff have also been removed from duty at the prime minister's office for suspected involvement in the attempted military coup, while 492 personnel were removed by Turkey's religious affairs directorate.

The Turkish army said in a statement that the armed forces have fully quashed all initiatives by the Gulen movement, and added that those involved in the coup attempt will be severely punished.
