As a result, activists and others are going to prison for more than 30 years in some cases, Business Insider reported on Friday.

On August 16, Saudi national Salma el-Shabab, a PhD student at Leeds University, was sentenced to 34 years in prison for tweets "in support of activists and members of the kingdom's political opposition in exile," the report said. Though the posts were made while she was in the UK, el-Shabab was nonetheless reported through the "Kollona Amn" app and immediately arrested upon returning home. 

"Every day we wake up to hear news, somebody has been arrested, or somebody has been taken," Real, a Saudi women's-rights activist using an alias, told Insider.

Kollona Amn – which roughly translates to "We Are All Security" in Arabic – was launched by the Saudi Interior Ministry in 2017, but the last few years have seen a "dramatic" surge in court cases referencing the app, according to legal-rights activists.
