Maoist insurgents blew up a railway station and disrupted public transport across several Indian states on Wednesday, on the second day of a strike that highlighted their growing strength and national coordination. The insurgents used powerful explosives to blow up Biramdih railway station in a pre-dawn attack in the eastern state of West Bengal, disrupting links with many parts of east and south India, officials said. “Dozens of Maoist rebels tied up all the railway employees and just blew the station and torched whatever was left of it before melting into darkness,” said Mahabir Pyne, a local resident. Maoists called the two-day strike in their strongholds of east and central India to protest against special economic zones (SEZs), low-tax enclaves created to boost industrial growth that have sparked protests from farmers who will lose their land. In the southern state of Andhra Pradesh, rebels called out employees of a coffee extracting plant from work near the port city of Vishakhapatnam, an SEZ location, and blew it up.
