Nicosia, Sept 13: Iranian Oil Minister Gholam Hossein Nozari on Friday has given a stern warning to Austrian energy firm OMV that unless it signs a deal on the Nabucco gas pipeline soon, Tehran will look for other partners.

The aim of the Nabucco pipeline is to transport at least 30 billion meters of natural gas per year from the Caspian Sea to Europe, bypassing Russia. OMV, the giant energy firm of Austria, is one of the six Nabucco partners.
