A cargo ship with 15 people on board sank in the Makassar Strait of central Indonesia, leaving 11 people missing, an official said on Saturday.

Iran PressAsia: The ship was hit by huge waves while sailing in the waters between Kalimantan island and Sulawesi island on Monday but the accident was found out by a passenger ship which helped the victims on Friday, said Dendy Prasetyo, senior press official at South Kalimantan's search and rescue office.

"Today (Saturday) we carried out a search and rescue operation to look for the 11 missing persons," he told Xinhua over phone.

Four people survived the accident, as they used a lifeboat and were helped by a ferry, said Prasetyo.

The cargo ship loaded with cement departed from a seaport in South Kalimantan province and was heading to a seaport in South Sulawesi province, according to the official.
