At least 11 villagers were killed and 45 injured in clashes with armed police in the Indian state of West Bengal on Wednesday in the worst violence seen over government plans to acquire farmland for new special economic zones.

Police shot teargas and live rounds at protesters preventing them from entering villages in the Nandigram area of the communist-ruled state, site of a proposed 10,000-acre SEZ to be developed by Indonesia’s Salim Group.
