Singapore has deployed a submarine rescue vessel to help with search operations for an Indonesian Navy submarine KRI Nanggala that has gone missing, the city-state's defence minister said in a post on social media on Thursday.
"The Republic of Singapore Navy's MV Swift Rescue – our submarine rescue vessel – was dispatched expeditiously yesterday (Wednesday) afternoon, as fast as she could get ready, after our Navy Chief received a request for assistance from his Indonesian counterpart," Ng Eng Hen posted on Facebook.
"The site for search operations, near Bali, is more than 1,500 kilometres away and waters are deep, which is why MV Swift Rescue sailed off as soon as she could."
Australia has also offered to support the search operation.
Australian Foreign Minister Marise Payne said the country would provide whatever support it could to Indonesia.
"We are obviously very concerned about these reports. It's very distressing for families and particularly for the Indonesian Navy," she said, quoted by ABC News.
"We've indicated that we will help in any way we can. We operate very different submarines from this one, but the Australian Defence Force and Australian Defence organisation will work with defence operations in Indonesia to determine what we may be able to do.
"We will go to the support of our neighbour in any way we can."
