On Monday, the Court ruled out extradition of three other Turkish servicemen with judges and a prosecutor having decided that the lives of the Turkish officers would be under threat in case of extradition. The future of the remaining two Turkish soldiers is yet to be decided.
"Why did it happen like that? We need to see the reason behind it. We are closely following the issue. Our expectation is that all of them would be extradited [to Turkey]," Cavusoglu said, as quoted by the Anadolu news agency.
All eight Turkish servicemen have denied their involvement in the coup attempt, but said they face prosecution in Turkey due to the government's post-coup crackdown. Ankara has repeatedly demanded their extradition.
On July 15, a military coup attempt took place in Turkey. Ankara accused Islamic preacher Fethullah Gulen, who has been living in the US state of Pennsylvania since 1999, and his followers of playing a key role in the coup. Since July, Turkey has arrested hundreds of military personnel, activists and journalists on suspicion of links with Gulen.
