Sensex gains 1.7 percent; energy firms rally

MUMBAI (Reuters) - The BSE Sensex rose more than 1 percent on Thursday to its highest in a week as energy firms such as Reliance Industries rose on expectations that the government would announce an increase in domestic prices of gas.

Broader sentiment was supported by data showing the 2012/13 current account deficit was lower than expected.

Reliance Industries provisionally rose 3.2 percent, while Oil and Natural Gas Corp ended up 4.2 percent.

The BSE Sensex provisionally gained 1.7 percent, its highest gain since June 19.

The 50-share NSE Nifty ended up 1.61 percent, posting its biggest daily percentage gain since June 14.
