Saudi Arabia has warned pilgrims not to mix politics with religion while performing Hajj.

During a meeting of the Saudi Cabinet, chaired by King Salman, pilgrims were urged to be considerate of the privacy and spirituality of the holy places and not to engage in political acts.

The warning follows a veiled threat by Iran’s Supreme Leader Ali Khamenei of disruption and possible political demonstrations by Iranian pilgrims at this year’s Hajj, and criticism of Saudi organization of the pilgrimage.

Saudi Minister of Media, Turki Al-Shabanah, called on worshippers to refrain from taking part in any political activities — such as the raising of slogans — that might disturb the pilgrimage.

“The Kingdom would not accept such behavior, and would take all necessary action to prevent misconduct,” said Al-Shabanah

Chairing the ministerial meeting in Jeddah, King Salman welcomed pilgrims and directed all Hajj organizing bodies to continue providing security, stability and tranquility for the visitors.
