Why diesel,Kerosine, LPG prices shoot up abnormally.?

I think main reason for for price rise of diesel, kerosene and lpg is rise in the price of crude oil in international market. So increase in prices of petroleum products is not avoidable. India needs to import 84% of total crude oil requirement. In 2010 international price was $75 per barrel. The price has gone up to $110. Without adjusting oil prices, the oil supplies may run into problem.
