US Vice President Mike Pence and Prime Minister Binali Yıldırım held a meeting in White House on Thursday, in which they discussed the issues of the extradition of Fetullah Gülen, the leader of Gülenist terror group (FETÖ) who has been living in Pennsylvania since 1999, weapons the US provides YPG terrorists and the recent visa crisis.

"It was a very productive meeting, we discussed all the problems encircling our bilateral relations," Yıldırım said.

"We have reiterated that the recent deterioration in our bilateral ties benefit neither Turkey nor the US," he added, touching upon the visa spat which was ignited by the arrest of Metin Topuz, an employee in US' Istanbul Consulate General.

"We expect normalization in visa crisis, and Mr. Pence has a positive stance on finding a solution," Yıldırım said, adding that he invited him for a visit to Turkey.

"We have requested a concrete step in extradition of Gülen," he said, mentioning the fugitive preacher living in a 400-acre compound in Saylorsburg and runs a shady network which orchestrated last year's coup attempt that left 250 people and more than 2200 injured.

"We also received promise from Pence to keep better track of weapons provided to the YPG," Yıldırım said. On the other hand, Pence also touched upon the matter, saying that they understand Turkey's sensitivities.

"We understand Turkey's sensitivity about the YPG. Our partnership with them is temporary and will last only a little longer now that Raqqa operation is complete," he said.
