U.S. Justice and State Department officials will fly to Ankara to discuss Gülenist terror-cult leader Fetullah Gülen's extradition process, according to a Justice Department official.

"U.S officials, including representatives of the Departments of Justice and State, have offered to consult with the Turkish government," the Justice Department official said, speaking on the condition of anonymity.

"We can confirm that a delegation (with) representatives of the Department of Justice and State will visit Turkey," the official added, but declined to give any date for the visit.

On Friday, Bloomberg news reported that the U.S. Justice Department would dispatch a team to Turkey in the coming days to pursue the accusations.

Ankara has repeatedly asked for the terror leader's extradition from the U.S. despite a standing treaty between the two NATO allies. After U.S. Secretary of State John Kerry said Washington wants to see "evidence, not allegations", Ankara responded by sending two batches of official documents to satisfy Washington's request.

On July 15, a Gülenist faction, led by the U.S.-based figure Fetullah Gülen, within the Turkish military attempted a deadly coup that killed more than 240 people and injured nearly 2,200 others.

Testimony from leading figures which sent to U.S. involved in the coup attempt point to Gülen as being responsible for the attempted coup, but America continues to display reluctance in regards to his extradition, demanding that Turkey provides "hard evidence."
