Turkey's ruling Justice and Development (AK) Party and opposition Republican People's Party (CHP) and Nationalist Movement Party (MHP) on Wednesday called on the international community to recognize Jerusalem as Palestine's capital.
"We call on the Organization of Islamic Cooperation (OIC) and all other countries to recognize East Jerusalem as the capital of an independent Palestine which is still under occupation, and the borders of which were defined in 1967," said the political parties in a joint declaration.
The parties recalled that the parliament had issued a joint declaration on Dec. 6 against the U.S. move recognizing Jerusalem as the Israeli capital.
The AK Party, CHP and MHP jointly occupy overwhelming majority of seats in the Turkish parliament.
Last week, Trump announced his decision -- despite widespread opposition -- to formally recognize Jerusalem as Israel's capital and relocate Washington's embassy from Tel Aviv to the holy city.
The announcement sparked strong condemnation from around the world, including Turkey, the EU and the UN.
The declaration comes following a 57-member OIC meeting which Turkey hosted on Wednesday to develop a unified Muslim position on Trump's policy shift.
