Liquefied Petroleum Gas (LPG) prices have been increased once again surging by 3 rupees in Punjab and 5 rupees per kg in NWFP and Sindh as rising cost of production forces producers to reduce output by another hundred tones. Chairman LPG distributors association, Abdul Hadi Khan told media that producers have decreased their output by 500 tones in a period of just 35 days. Now, daily production stands at 1700 tones which is able to meet summer demand but will not be sufficient for winters.
