More than 40 United States Congress members have written a letter to Secretary of State Marco Rubio, urging him to intervene in the case of Sama Safi, a 20-year-old US citizen who has been detained without charge by Israeli military since June. The legislators, led by Congresswoman Rashida Tlaib, expressed concern over Safi's deteriorating health under "appalling conditions" in custody. They urged Rubio to use every available tool to secure her immediate release for medical treatment and return to her family. Israel has received approximately $25 billion in US military aid since October 2023, despite several incidents of violence against American citizens by Israeli forces or settlers that have gone unpunished. The letter highlighted Safi's chronic medical condition, Familial Mediterranean Fever, and her lack of regular access to medication while in detention. The State Department declined to comment on the specifics of the case citing privacy concerns but assured that the administration prioritizes the safety and security of US citizens abroad. Raed Jarrar, advocacy director at the US-based rights group DAWN, suggested suspending American military aid to Israel under Washington's regulations in response to Safi's detention. The Israeli government did not respond to Al Jazeera's request for comment by publication time.
