Oji said that the primary agreement on the project was reached last week in Baghdad and in the future the official agreement will be signed by the oil ministers of the three countries, said Shana.

Under the deal, natural gas produced in Iran's South Pars oil and gas field will be pumped through Iran, Iraq and Syria to Lebanon and the Mediterranean Sea before reaching Europe, he said, according to local satellite Press TV's Wednesday report.

The construction of the 5,600- kilometer (3,480-mile) pipeline is estimated to cost $5 billion to $6 billion, he said.

Oji said the pipeline would ultimately have the capacity to pump 110 million cubic meters of natural gas per day, said Press TV.  

Iran has the world's second largest gas reserves after Russia but has struggled for years to develop its oil and gas resources.
