US Secretary of State Mike Pompeo on Wednesday said he expects a decision soon regarding US sanctions imposed on Turkey, suggesting that they may be removed. 

While speaking to reporters as his plane refueled in the Belgian capital Brussels, Pompeo noted that the US will have a decision on the sanctions shortly. 

Noting that some of those sanctions were directly connected to Ankara's detention of an American pastor who was released last week, Pompeo said "There's a logic to now moving those as well."

But the US top diplomat also pointed out that no final decision has been made and he will need to talk to the US president about that. 

Pompeo made the remarks while speaking to reporters after meeting with Turkey's president and foreign minister earlier on Wednesday, days after US pastor Andrew Brunson was released.

While Pompeo welcomed Brunson's release in meetings with Turkish President Recep Tayyip Erdogan and Turkish Foreign Minister Mevlut Cavusoglu, according to the US State Department, he also raised concerns about others being held in Turkey, including a Turkish-US scientist who had worked for the National Aeronautics and Space Administration (NASA).
