Assem Mohammed is a journalist from Yemen. He was arbitrarily arrested on 21 May 2025 in Al-Hudaydah Governorate by an armed group affiliated with the Houthis without any judicial warrant as part of a coordinated sweep targeting around 13 journalists and media professionals. He has since been held in custody by the Security and Intelligence Service in Al-Hudaydah, without charge. The Yemeni Journalists Syndicate condemned the operation on 25 May 2025, calling it a direct assault on journalists and freedom of opinion and expression. Local sources highlight that Assem had reported on sensitive civic and humanitarian issues in the region, and his detention is emblematic of the broader pattern of repression and impunity facing media workers across Houthi-controlled areas.
