Twelve people, a pregnant woman and eleven men, involved in women's rights activities or supportive of the imprisoned activists were arrested on or around 4 April 2019.[1] The arrestees, including two United States (US)–Saudi binational citizens, Badr al-Ibrahim and Salah al-Haidar, son of Aziza al-Yousef, were seen as not being "front-line activists", in the sense that they were not politically active on Twitter and were rarely quoted in non-Saudi media.[2]
