"India did not take part at the tripartite meeting at Teheran on September 24 to finalise the Iran-Pakistan-India gas pipeline project, envisaging supply of natural gas via Pakistan, but for US pressure", Yechury alleged in an article in the party mouthpiece Ganashakti on Monday.

"The deal has been finalised between Iran and Pakistan on Saturday. It is unwise for India to remain absent at that meeting", the CPI(M) leader, here to attend CPI(M) politburo and central committee meetings, said.

Alleging that the US "has been determining India's foreign policy", he said: "This has vindicated our party's observation that implications of the proposed Indo-US nuclear deal will not be limited within nuclear energy alone, but to other wide areas too".

He alleged that it was at the instance of Washington that India had voted against Iran twice at the IAEA meeting.

He said the US had been openly opposing the Indo-Iran gas pipeline project to import natural gas.

Though the External Affairs Minister Pranab Mukherjee had said that there was no relation between the gas pipeline project and the Indo-US Nuclear deal, "in effect, it is being seen that India has been dilly-dallying on this project after succumbing to the US pressure", he said.

The daily quoted Yechury as saying, "while Pakistan President Pervez Musharraf could conclude a deal with Iran being a friendly ally of President Bush, why couldn't we?"
