The price of Brent oil fell below the benchmark level of $75 per barrel upon the announcement.
An OPEC meeting was held in Vienna, where the group's member countries gathered to discuss a possible curb of oil output amid the falling of oil prices by about $40 per barrel on the global market.

On Tuesday, a separate meeting between OPEC-members Saudi Arabia and Venezuela, and non-members Russia and Mexico was held, however, it did not result in an agreement to curb output.
OPEC currently has 12 member states, namely Algeria, Angola, Ecuador, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates and Venezuela. OPEC controls some 40 percent of the world’s oil output.
The OPEC accounts for a third of global oil output.

One of the reasons for the current decline in oil prices is the speculative factor amid strengthening of the dollar and uncertainty in global economic growth, Libyan Vice Prime Minister Abdourhman Ataher Ahirish stated Thursday.
"Ample supply, moderate demand, a stronger US dollar and uncertainties about global economic growth have been key factors in this recent price trend.
