(CNN) Turkey has joined a growing chorus of key US allies in warning President Donald Trump about the perils of recognizing Jerusalem as the capital of Israel, describing it as a "fatal mistake" that would spark fresh conflict in the Middle East.

Turkish President Recep Tayyip Erdogan said Tuesday that a reported plan for such recognition, in whole or in part, would be a "red line for Turkey" and could lead to Ankara cutting diplomatic ties with Israel.

"As the temporary president of the Islamic Cooperation Organization, we will follow this issue very closely," Erdogan said at his party's weekly meeting in the Turkish capital.

In a series of tweets earlier on Tuesday, Turkish presidential spokesman Ibrahim Kalin described the reported plan as "a fatal mistake ... such a move would undermine all peace efforts and trigger new tensions and conflicts."
