JAKARTA, Sept 3 (Reuters) - Indonesia will raise the domestic price of subsidised fuels by about 30%, its energy minister said on Saturday as the government moves to rein in ballooning subsidies despite a risk of mass protests.

Effective an hour after the announcement, the price of subsidised gasoline will rise to 10,000 rupiah (67 U.S. cents) a litre from 7,650 rupiah, while that of subsidised diesel will increase to 6,800 rupiah a litre from 5,150 rupiah, energy minister Arifin Tasrif said.
