Iraq's judiciary has sentenced a man to 15 years in prison for the kidnapping of an American journalist who was abducted earlier this year by a powerful Iran-backed group, a judicial source said Monday. At the height of the Middle East war, on March 31, Kataeb Hezbollah kidnapped journalist Shelly Kittleson in Baghdad, holding her for several days before setting her free just hours before the United States and Iran agreed to a ceasefire. Iraqi authorities arrested one member of the group at the time. According to a document shared by local media, a criminal court on Sunday sentenced Amir Rahim Jabbar to 15 years in prison under an "anti-terrorism law... for the crime of kidnapping" Kittleson. A judicial source verified to AFP the document's authenticity, and a Kataeb Hezbollah source confirmed the ruling against one of its members. Kittleson, who shared a copy of the ruling on X, said she was "grateful to the Iraqi judiciary". Kataeb Hezbollah is among several pro-Iran armed groups that intervened in support of Tehran during the Middle East war, claiming attacks on US facilities in Iraq and across the region. Under mounting US pressure to curb Tehran's influence, the new Iraqi government of Prime Minister Ali al-Zaidi says it is committed to ensuring that pro-Iran armed groups, which Washington designates as terrorist organisations, hand over their weapons to the state. The issue has fuelled tensions in Iraq, with several groups, including Kataeb Hezbollah, refusing to disarm. Earlier this month, Kataeb Hezbollah accused Zaidi of engaging in "provocative and irresponsible actions". Baghdad was once notorious for kidnappings and attempted abductions, but they have decreased as the security situation in Iraq improved in recent years.
