Talks aimed at salvaging a India-US nuclear cooperation deal continued into a third day, and US officials said negotiators were making progress.
A State Department spokesman, Tom Casey, said officials had decided that the progress warranted an extra day of negotiations.
Late Thursday, Undersecretary of State Nicholas Burns said negotiators were close and would continue talking into the night.
“We have overcome many of the outstanding issues,” he said.
“We just need to go the extra feet.”
The meeting later broke up with no announcement of results.
The negotiations have followed a rare foreign policy victory for President George W Bush late last year when Congress approved a proposal to ship US civilian nuclear fuel to India.
Negotiators are working to settle technical details on an overall cooperation plan.
One major sticking points has been US reluctance to allow India to reprocess spent atomic fuel, a crucial step in making weapons-grade nuclear material.
