Imphal, November 23 (IANS): Manipur on Thursday faced an acute shortage of fuel following a strike by owners of oil tankers in protest against government policies. Most petrol pumps remain closed on Thursday but officials said there was enough stock to last 21 days. A Tamphayai, Secretary of the All Manipur Petroleum Products Transporters Association, said: "The government has slashed the transportation charge by 14 per cent of the amount fixed in 2013. And the security deposit by each transporter was hiked from Rs 3 lakh to Rs 5 lakh." Although the petrol pumps were shut, roadside fuel vendors continued their illegal business.
