Since the start of the Shia insurgency, many people accused of supporting al-Houthi have been arrested and held without charge or trial. According to the U.S. State Department International Religious Freedom Report 2007, "Some Zaydis reported harassment and discrimination by the government because they were suspected of sympathizing with the al-Houthis. However, it appears the Government's actions against the group were probably politically, not religiously, motivated."
