Iraq offers to supply half of Nabucco's gas

Iraq has offered to supply enough gas to fill half the capacity of the proposed Nabucco pipeline, giving the project a boost even as heads of government met to sign a historic agreement approving the plan.

The offer from Nouri al-Maliki, Iraq's prime minister, to supply 15bn cubic metres of gas a year by 2015 helps address the greatest obstacle to the 3,300km pipeline from eastern Turkey to Austria: the prospect of there not being enough gas to fill it.

José Manuel Barroso, pre-sident of the European Commission, said the signing of the Nabucco agreement in Ankara by the leaders of five countries on the pipeline's route - Austria, Bulgaria, Hungary, Roman-ia and Turkey - could "open the door to a new era in the relationship between the European Union and Tur-key, and indeed beyond".
