An Iranian court issued a USD 312.9 million judgment against the US over a 2017 Islamic State-claimed attack on Tehran, authorities said Wednesday following the latest judicial action between the nations amid their decadeslong enmity.

Iran’s state-run IRNA news agency, in reporting the decision, offered no direct evidence to support the court’s allegation that American officials had any part in the June 2017 attack that killed at least 18 people and wounded 50 others. The assault saw gunmen attack Ayatollah Ruhollah Khomeini’s mausoleum and the country’s parliament, starting a siege that continued for hours.
