Jerusalem: Turkey warns Trump against crossing 'red line'

Turkey's president has warned it could sever ties with Israel if the US recognises Jerusalem as its capital.
Recep Tayyip Erdogan said such a move would cross a "red line" for Muslims.
Donald Trump called world leaders on Tuesday amid a growing chorus of warnings against taking the step.
Reports say the president will dramatically shift the US position on the status of Jerusalem this week. Its fate is one of the thorniest issues between Israel and the Palestinians.
Israel has always regarded it as its capital city, while the Palestinians claim East Jerusalem as the capital of a future Palestinian state.
If Washington recognises Jerusalem as Israel's capital, it would be the first country to do so since the foundation of the state in 1948.

What is so contentious about Jerusalem's status?
The status of Jerusalem goes to the heart of Israel's conflict with the Palestinians, who are backed by the rest of the Arab and wider Islamic world.
The city is home to key religious sites sacred to Judaism, Islam and Christianity, especially in East Jerusalem.

What has been the international reaction?
French President Emmanuel Macron told Donald Trump he is "concerned" the US leader could unilaterally recognise Jerusalem as Israel's capital, saying any decision on its status must be "within the framework of negotiations between Israelis and Palestinians".
The European Union, part of the so-called Middle East Quartet of mediators which includes the US, the UN and Russia, warned of "serious repercussions on public opinion in large parts of the world".
Arab League chief Ahmed Aboul Gheit warned it would be "a dangerous measure that would have repercussions".
Saudi Arabia said such a move before a final settlement in the Israeli-Palestinian conflict would "have a detrimental impact on the peace process".
Palestinian President Mahmoud Abbas has urged world leaders to intervene, saying "such a US decision would destroy the peace process".
Jordan, custodian of Islamic sites in Jerusalem, has warned of "grave consequences".
