Shabiha have been reported of killing and perpetrating sectarian massacres of Sunnis.
In addition, there have been numerous reports of sectarian violence against Sunnis by non-government Shiite Islamist groups, which have sought to justify their war-crimes by declaring that "We are performing our taklif [religious order]".[64] In one incident in late January 2012, Reuters reported that 14 members of a Sunni family were killed by the shabiha along with 16 other Sunnis in a formerly mixed neighbourhood of Homs that Alawites had purportedly fled four days prior.[65] Documented incidents of the regime's security forces targeting Sunni districts and villages date back virtually to the start of the uprising, including the shelling of Sunni neighbourhoods in Latakia by gunboats of the Syrian Navy in August 2011.[66] Abandoned Sunni homes have also been systematically plundered to the extent that "the country's newly flourishing flea markets took on a new name, "souk al sunna."
The massacres in Houla and Qubeir, both Sunni farming settlements on the fault line between Sunni majority areas and the Alawite heartland of the Alawite Mountains, are said to be part of a plan intended by radical Alawite elements in the north-west to clear nearby Sunni villages in order to create a "rump state" that is easy to defend.[68] The Naame Shaam campaign has sought to highlight the sectarian nature of the Syrian government and the sectarian role of its main ally Iran, which includes attempts to alter the demographic composition of areas of Syria via the removal of Sunni inhabitants.[69]
Describing reports of Hezbollah-led ethnic cleansing campaigns across Syria, US chair of the United States House Committee on Foreign Affairs, Ed Royce, stated in December 2015: "I’ve been briefed on the fact that [Iran is] even bringing in militias from Hezbollah and their families into Sunni dominated neighborhoods in Damascus and running their Sunni population out as they basically do an ethnic cleansing campaign".[74] SNHR reported in 2017 that the war has rendered around 39% of Syrian mosques unserviceable for worship. More than 13,500 mosques were destroyed in Syria between 2011-2017. Around 1,400 were dismantled by 2013, while 13,000 mosques got demolished between 2013-2017.[75]
In 2018, The Economist reported that most of the Syrians forcibly displaced by the Ba'athist regime belong to the Sunni community as part of a systematic sectarian cleansing campaign to re-mold the demography in favour of the Assad dynasty. Hardline Assadists often justify the bombings in Sunni-majority regions by labelling the Sunni residents as "terrorists". Law No. 10 implemented by the regime has dispensed out thousands of homes and properties owned by displaced Sunnis to Iran-backed Khomeinist militants and pro-Assad loyalists
The controversial Law No. 10 passed by Bashar al-Assad in 2018 enabled the state to confiscate properties from displaced Syrians and refugees if they do not submit official documents within a timeframe of 1 year. The law is widely viewed as part of a social engineering campaign to remake Syria in the image of Bashar al-Assad, particularly by preventing the return of Sunni refugees. There are reports of regime plans to make Sunnis a minority within Syria in-order to consolidate its rule through the weaponization of Law no.10 and distributing vast swathes of confiscated properties to Assad loyalists and pro-Iranian militants.[a] Increasing sectarian violence has also resulted in Sunni holy places being attacked by Syrian and foreign Shia militias and the Syrian Army. Middle East Monitor reported in 2020 that graveyards of numerous Sunni figures have been demolished as revenge for the alleged destruction of Shia shrines.[84] In May 2020, eighth century Umayyad Caliph Umar ibn Abd al-Aziz's tomb in Idlib was destroyed by the Syrian Arab Army and Iranian-backed Shia militant groups.[84][85][86][87][88][89]
