Prime Minister Binali Yildirim delivered a speech at a news conference in Seoul.
U.S. President Donald Trump is due to formally recognize Jerusalem as the Israeli capital later Wednesday and begin preparations to move the embassy from Tel Aviv, three senior U.S. officials confirmed late Tuesday.
Yildirim said: “One way or another, both [these] situations will be unlawful decisions and will make the existing problems in the region even more intractable.
“The U.S. president to not make a statement in this direction is vital for the future of the region and global peace.
“Jerusalem is a very delicate subject in the Islamic world. Our biggest expectation and hope on this matter is that no steps are taken. Impositions, wrong steps in this direction would bring irreversible consequences.”
“Along with the entire Muslim world, we will continue to stand by our Palestinian brothers in their just cause, just as we have done until this day,” Yildirim said.
Speaking in Brussels, Foreign Minister Mevlut Cavusoglu told journalists the move would “bring chaos to the region instead of stability and peace”.
Cavusoglu, who will meet U.S. Secretary of State Rex Tillerson on the sidelines of a NATO foreign ministers’ meeting, added: “Not only the Muslim world but the whole world stands against this.
“I have spoken to U.S. Secretary of State Tillerson before [about this issue] and I will discuss it again when I meet him.”
Later, Deputy Prime Minister Bekir Bozdag, who acts as government spokesman, said the declaration of Jerusalem as Israel’s capital would be a “great disaster for all of us and everyone.”
He tweeted: “The declaration of Jerusalem as the capital will destroy the peace process that has been conducted with great difficulty.
“It will pave the way for great turmoil, crisis, chaos and conflict in the region and foreshadows unseen negatives. In short, the declaration of Jerusalem as the capital will be a great disaster for all of us and everyone.”
Bozdag called on Muslims and Muslim governments to “protect their honor”.
“I invite everyone to act responsibly, stick to the agreements signed, act with wisdom, to avoid risking world peace for domestic politics or any other reason and refrain from acting for own interests,” he tweeted.
“I invite Muslims and Islamic countries to protect their honor.”
Meanwhile, other ministers lined up to condemn the decision.
Justice Minister Abdulhamit Gul called the proposed change “unacceptable” while Health Minister Ahmet Demircan, speaking in Saudi Arabia, said it would be a “great violation” of international law and UN resolutions and called on Washington to back down from a “mistake”.
