Turkish President Recep Tayyip Erdogan on Friday berated the Arab countries that back U.S. President Donald Trump's Middle East plan, charging it as "treasonous."

"Some Arab countries that support such a plan commit treason against Jerusalem, as well as against their own people, and more importantly, against all humanity," Erdogan told his party members in Ankara.

Erdogan, a staunch critic of Israeli policy toward the Palestinians, described the Muslim countries' stance toward the Trump plan as "pitiful," citing Saudi Arabia, Oman, Bahrain and the United Arab Emirates.

"Saudi Arabia in particular, you are silent. When will you speak? You look at Oman, Bahrain and likewise Abu Dhabi," charged the Turkish president.

"Shame on you! Shame on you! How will those hands that applaud (the Trump plan) give an account of this treasonous step?"

Ankara categorically rejects the plan that "basically destroys Palestine as a whole and seizes Jerusalem," Erdogan added.

Trump this week unveiled a plan for the Middle East, which would give Israel control over the West Bank and Jordan Valley as well as key holy sites in Jerusalem. The Palestinians rejected the plan.

"If we fail to protect the secrecy of al-Aqsa [mosque] today, we will not be able to prevent evil eyes from turning to Kaaba tomorrow," Erdogan added, referring to the two of the holiest cites in Islam.

Kaaba, or House of God, in Mecca is where Muslims face for their daily prayers. The al-Aqsa Mosque area in Jerusalem is the third holiest site in Islam.

"That is why we say Jerusalem is our red line."
