MT Desh Shanti, belonging to the Shipping Corporation of India (SCI), was detained by Iran at Bandar Abbas Port on August 12 for alleged pollution. It was released on September 6.

The vessel, which can carry 1,40,000 tonnes of crude, was detained by the Iranian Revolutionary Guards Corps in the Persian Gulf while carrying oil from Basrah in Iraq to Visakhapatnam.

It was released after SCI, India's largest shipping company, submitted a letter of undertaking to the Iranian Ports and Maritime Organisation.
