The U.N.´s top official for Libya on Monday called for lifting the production blockade at two oil fields including the country´s largest, as oil prices soared to over $130 a barrel.

Stephanie Williams, the U.N. special adviser on Libya, said blocking oil production from the Sharara and el-Feel fields “deprives all Libyans from their major source of revenue.”

The shutdown came as Brent crude, the international pricing standard, hit $139.13 per barrel before falling back Monday to be traded at $130.29 a barrel.

The growing increase of oil prices is a consequence of the Russian invasion of Ukriane, which sent shockwaves to the world markets.
