Secretary-General of Organization of the Islamic Cooperation was asked to help stop Saudi government from execution of Shia religious leader Shiekh Nimr.

They expressed deep regret at hearing the bad news on execution sentence against the Arab ayatollah, who is 'famous for his peaceful approaches and defense for the rights of the minorities.'

'As your excellency are well aware, killing individuals for expression of their beliefs, or merely because of participation in peaceful demonstration is not against the internationally declared human rights principle and the Islamic beliefs, as they are reiterated in the Cairo Islamic Human Rights Declaration,' reads the letter in part.

Saudi Supreme Court on Saturday confirmed death sentence of Sheikh Nimr, one of prominent Shia religious leader in the country.

Brother of Sheikh Namar a couple of days ago in Cairo described the verdict as unjust and called for his brother's immediate release.

Saudi people along with amnesty international and legal organizations have called for freedom of Sheikh Namar.

The verdict has been condemned by world public opinion and the international human rights organizations; IRNA reported.
