Doesn't change the fact that it still hasn't confirmed by the TNI-AL yet.The twitter account look like coming from specialized maritime media, journalist in that media I believe has good and credible sources inside Navy.
It reminds me of any news about accident or missing planes or ship in this country. There were always other sources who claimed such and such, creating from false hope to even more despair. While some might be born out of good intention, but the result is still the same: creating unnecessary confusion.
That's the last thing the public need.
