Yemen approved on Tuesday an increase in the prices of domestic gas by YR 100 per cylinder; almost two weeks after the prices of diesel and petrol rose by YR 100 per 20 liters.
One cylinder is now sold for YR 750.
In a related move, Parliament approved to summon the government on Wednesday to give explanations for increasing prices as well as the shortage of gas.
About 40 MPs signed a request to convene the government.
Filling stations suffered an acute shortage of diesel on Tuesday, with queues seen at many of them and others shut down amid unavailable petrol.
Filling stations owners blamed lack of fuel quantities supplied by the Yemen Gas and Oil Company for the crisis.
The gas shortage started to surface after Yemen inaugurated the biggest ever LNG project in its history, exporting the firstfruits from the LNG Plant in Shabwa in the south to South Korea in mid-October 2009.
The multi-billion dollar project in which the French TOTAL company is the prime shareholder of more 43 per cent is the second LNG project in the Arab World after Qatar's.
