The recognition will "throw the region and the world into a fire and it's not known when it will end", Deputy Prime Minister and government spokesman Bekir Bozdag wrote on Twitter.
President Donald Trump told Palestinian Authority President Mahmoud Abbas on Tuesday that he intends to move the US Embassy in.
Turkish President Recep Tayyip Erdogan has invited leaders of member states of the Organization of Islamic Cooperation (OIC) to attend extraordinary meeting on Wednesday to discuss the status of Jerusalem. The recent move has been opposed by a number of world powers, including Turkey and the Arab League.
The US intention to move its embassy to Jerusalem is a sign of its incompetence and failure, Iranian Supreme Leader Ayatollah Ali Khamenei said Wednesday, according to his official website. "We hope the US administration will avoid this mistake".
Speaking from Seoul where he met his South Korean counterpart, Yildirim said: "One way or another, both situations will be unlawful decisions and will make the existing problems in the region even more unsolvable".
Istanbul, Dec 6 The expected US move to recognise Jerusalem as the capital of Israel risks igniting a "fire" in the Middle East and will prove a "great disaster", the Turkish government said today.
Last year, Turkey and Israel ended a rift triggered by Israel's deadly storming in 2010 of a Gaza-bound ship that left 10 Turkish activists dead and led to a downgrading of diplomatic ties.
"In the face of developments that arouse sensitivity over the status of Jerusalem, Mr President is calling a leaders' summit of the Organisation of Islamic Cooperation (OIC) in order to display joint action among Islamic countries", presidential spokesman Ibrahim Kalin told reporters in Ankara. In 1967, after the Six Day War, it seized East Jerusalem and united it with the West Jerusalem, but the UN did not recognize this.
Israel claims the entire city as its undivided capital, while the Palestinians want the eastern sector as the capital of their future state.
