Ayatollah Seyyed Ali Khamenei, Leader of the Islamic Revolution The Leader of the Islamic Revolution has said the bombing of the holy Shia shrines in Samarra is aimed at provoking sectarian violence.
In a message on the recent bombing of the shrines of the two revered Shia Imams in the Iraqi town of Samarra, Ayatollah Seyyed Ali Khamenei blamed the intelligence services of the Zionist regime and the occupation forces in Iraq for the bombing, saying such terrorist acts are meant to intensify sectarian violence in the Muslim world.
The Leader urged the Muslims particularly the Iraqi people to remain vigilant in the face of the plots hatched to create sectarian strife between Shias and Sunnis.
He noted the holy shrines of the two revered Shia Imams in the Sunni town of Samarra, had been respected throughout history, whereas the recent event marks the second desecration of these holy sites since the invasion of Iraq by foreign troops.
He emphasized that the occupying forces are instigating insecurity in Iraq and leaving enough space for terrorist movements in order to justify the ongoing illegitimate occupation of the country and to debilitate the government of Iraq.
Calling for Sunni scholars to condemn the sacrilege of the holy sites and Shias to remain calm, Ayatollah Khamenei said our Shia and Sunni brothers in Iraq should beware of the conspiracy against the Muslim unity.

Grand Ayatollah Ali Khamenei, Iran's highest-ranking religious and political leader, blamed the intelligence services of the United States and Israel for the bombing of the Askari Mosque in Samarra, Iraq.  According to him, 

On 13th of June 2007, Iraqi insurgents blew up the two minerets of the Askari Mosque.  The shrine is important because it contains the remains of the Imam Hadi and Imam Askari.  The son of Imam Askari is Imam Mahdi.  This is especially important in the context of Iran's politics;  according to Article 5 of the Constitution of the Islamic Republic of Iran, Khamenei as an Islamic jurist is supposed to lead the "Ummah".  Some Muslims object to this.  For instance, one Islamic cleric has said that Khamenei "does not have a divine authority or right to determine the fate of other peoples and countries," referring to Muslims outside Iran.

Khamenei urged Sunni scholars to speak out against the sacrilege and Shia Muslims to remain calm.  He believes that this bombing of part of a conspiracy to fuel sectarian tensions.

Earlier, Sheikh Mohammad Hussein Fadlallah in Lebanon also made the same charge and said, "Without doubt, the occupiers are providing the grounds for Salafi Takfiri groups and intelligence agencies to pillage the country."
