Saudi forces have reportedly demolished at least 320 houses in an eastern Shia-majority town, according to local activists.

The sources said the structures in Awamiyah, which has been placed under siege for about three months, had mostly been populated by Shia Muslims.

They said Saudi forces also laid waste to four mosques and three Husainiyahs -- centers for Shia mourning rituals.

Located in the Qatif region of Saudi Arabia’s Shia-populated Eastern Province, Awamiyah has been the scene of anti-regime rallies since 2011, with protesters protesting the kingdom’s discriminatory policies against the country’s Shia minority.

Human Rights Watch (HRW) says Saudi Arabia’s siege on Awamiyah has raised concerns about the humanitarian situation there.

The New York-based rights organization reported on Sunday that the town’s residents are at risk, with Saudi security forces “arbitrarily shooting at or arresting those who emerged from their houses.”

“Saudi security forces should provide essential services to trapped Awamiyah residents and make sure they can move in and out of the town safely,” said Sarah Leah Whitson, Middle East director at HRW.

She also called on Riyadh to hold security forces accountable if probes showed that they had fired at residents unlawfully.

“Saudi authorities should also immediately and credibly investigate whether its forces used excessive force in Awamiyah,” Whitson noted.
