Indian activists of right-wing Hindu organisation Shiv Sena shout slogans as they burn an effigy of Indian Cabinet Minister for Petroleum and Natural Gas Jaipal Reddy during a protest against the petrol price hike in Amritsar on May 24, 2012. Indian state-run oil firms announced the sharpest hike in petrol prices in nearly a decade to offset growing losses caused by subsidised rates, rises in the international oil price and a plunging rupee. The increase was put at 6.28 rupees (11 US cents) per litre which, when taxes are included, will mean a 7.5-rupee hike for consumers in India from May 24.
