The Tasnim news agency reports that six Iranian crew members who were on board a US-seized container ship on April 20 have been freed and returned to Iran, according to Al Jazeera.

Another 22 Iranian crew members from the Touska vessel are still detained, and Iranian authorities are continuing efforts to secure their release, it says.

US Central Command and President Donald Trump claimed the Touska was targeted after it refused to follow US orders to withdraw from its planned passage through the Strait of Hormuz.
