Majority of commuters and motorists suffered on Wednesday as Compressed natural gas (CNG) dealers went on strike across the country against possible tax surcharge on the fuel gas from July. Responding to a countrywide strike call given by All Pakistan\'s CNG associations, CNG filling stations remained closed here and other major cities. Meanwhile, citizens face problems as transporters have increased the fares owing to the reason of running their vehicles on petrol and diesel, a relatively costly fuel.
