In Bahrain

Bahrain is ruled by the Al Khalifa family, who are part of the Sunni minority since 1783. Bahrain's Shia majority has often complained of receiving poor treatment in employment, housing, and infrastructure, while Sunnis have preferential status.^[1] The Bahraini government has reportedly imported Sunnis from Pakistan and Syria in an attempt to increase the Sunni percentage.^[1][2]

Shiite Muslims are blocked from serving in important political and military posts.^[2] Sunnis and Shia often stress that, no matter what their denomination, they are all Bahrainis first and foremost. However, sectarianism seethes below the surface of society.^[3]

Minor sectarian clashes have occurred during the Bahraini uprising. On 4 March 2011, about six people^[4] were injured in Hamad Town and police intervened to disperse young Shi'ites and largely recently naturalized Sunni Arabs who clashed with knives, sticks, and swords, witnesses said.^[5] It is unclear what caused the incident,^[6] with both sides blaming the other for the outbreak of violence.^[5] This incident marks the first sectarian violence since protests erupted on 14 February. A spokesman for Al Wefaq opposition party said the clashes were due to a dispute between families in the area and weren't sectarian. Others said that Shiite youth had targeted naturalized Sunnis living in the area.^[4]

In Indonesia

In Iraq

Following the 2003 Invasion of Iraq and subsequent fall of Saddam Hussein's regime, the minority Sunni sect, which had previously enjoyed increased benefits under Saddam's rule, now found itself out of power as the Shia majority, suppressed under Saddam, sought to establish power. Such sectarian tensions resulted in a violent insurgency waged by different Sunni and Shia militant groups, such as al-Qaeda in Iraq and the Mahdi Army. Following the U.S. withdrawal in 2011, violence has increased to 2008 levels.^[11] Following February 2006 tens of thousands of people were killed across Iraq, when a civil war between the two Muslim rival sects erupted, lasting until 2008.^[12]

In Saudi Arabia

The Grand Mufti of Saudi Arabia, Abdul-Aziz ibn Abdullah Al Shaykh, issued a fatwa on 12 September 2013 that suicide bombings are "great crimes" and bombers are "criminals who rush themselves to hell by their actions". Sheikh described suicide bombers as "robbed of their minds... who have been used (as tools) to destroy themselves and societies."^[13]

On 16 September 2013, he condemned violence against non-Muslims living in Islamic countries or Muslims labeled as infidels. The Grand Mufti condemned acts that cause the "shedding of blood of Muslims and of those living in their counties in peace." Sheikh Al Shaykh stated, "Given the dangerous developments in the Muslim world, I would like to warn against the danger of attacking Muslims and those (non-Muslims) under Muslim protection."

"In view of the fast-moving dangerous developments in the Islamic world, it is very distressing to see the tendencies of permitting or underestimating the shedding of blood of Muslims and those under protection in their countries. The sectarian or ignorant utterances made by some of these people would benefit none other than the greedy, vindictive and envious people. Hence, we would like to draw attention to the seriousness of the attacks on Muslims or those who live under their protection or under a pact with them," Sheikh Al-AsShaikh said, quoting a number of verses from the Qur'an and Hadith.^[14]

However, the Government of Saudi Arabia does discriminate against and/or persecute Shia Muslims,^[15] Ahmadiyya^[16] and even non–Salafist Sunni Islam.^[17]
