If you are in Batam right now, Saturday 27-04-2013, please be advised not to go Nagoya Hill mall today.There is a fire accident that is burning 2 shop houses next to JCO donuts. There was a huge explosion and cause is unknown yet as of now I am typing. The mall has turned off all electricity too.
There is no immediate danger but I would advise visiting other malls for today. I am pretty sure in a few hours time everything will be back to normal.
Be safe and happy traveling!
