More than 50 people, including the member-secretary of the National Committee to Protect Oil, Gas, Mineral Resources, Power and Ports, Anu Muhammad, were injured when police charged into marchers heading for Petrobangla headquarters in the capital midday Wednesday in protest against the government’s decision to award three offshore blocks to international oil companies.

About 1,000 leaders and activists of the committee gathered at Muktangan where they held a rally in the morning before marching towards the Petrobangla office at Karwan Bazar where the protesters were to lay siege.
