Tehran has secured the release of an Iranian-flagged tanker, seized by Indonesian maritime authorities earlier this year over allegations of illegal transfer of crude oil in the Southeast Asian country's waters.

“The MT Horse, belonging to the National Iranian Tanker Company that had been detained in Indonesian waters since January 24, was released on Friday,” the Islamic Republic of Iran Broadcasting (IRIB) news agency reported.

The report added that the vessel was released after a legal battle which lasted for 125 days, thanks to all-out efforts by senior Iranian officials as well as the Consular Affairs Department of Iran’s Foreign Ministry.

“This vessel has now resumed its mission before returning to the country’s waters,” it noted without giving further details.
