Ali Akbar Velayati, a senior advisor to Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei on international affairs, made the remarks in a conference on Islamic unity in the Iraqi capital, Baghdad, on Saturday.
Velayati said the Americans and Arabs are trying to create �a new Middle East, whose reality will be marked by the disintegration of Muslim societies.�
He said Washington was seeking to split Syria through its presence in the eastern Euphrates.
He also referred to US Secretary of State Rex Tillerson�s recent Middle East tour, saying the visit had been aimed at broadening the division among the Muslim Ummah and Muslim countries.

PressTV-Tillerson, Erdogan meet amid Syria offensive tensions
Top US diplomat Rex Tillerson and Turkey's President Recep Tayyip Erdogan have had a meeting to improve ties strained recently over their policies on Syria.
Velayati said the Americans were seeking to establish bases for the North�Atlantic Treaty Organization (NATO) with the help of Muslim states to prevent unity among these countries.
�The Americans and Zionists should know that as they were defeated in the Lebanon, Syria, and Iraq, their illusions won�t materialize. The resistance front in Iraq, Syria, and Lebanon will push them out of the eastern Euphrates,� he said.
Much of northeast Syria to the east of the Euphrates is controlled by the so-called Syrian Democratic Forces (SDF), which is dominated by the militants from the Kurdish People�s Protection Units (YPG) and is backed by the US.
The US announced last month that it would work with the SDF to set up a new 30,000-strong �border security� force along the Turkish border with Iraq and within Syria along the Euphrates River.
