Rejecting the notion that the Indo-US nuclear deal was in trouble, the Bush administration has asserted that it was 'firmly intact' and expressed confidence that there would be forward movement on it in next few months.

"I think that the US-India nuclear deal is firmly intact. It is going to be successful," US Under Secretary of State for Political Affairs Nicholas Burns, who was on a visit to Turkey, told a news conference in Ankara.

"We are going to move forward on it (the deal) and you will see that happen in the next few months," Burns said, according to a transcript made available in Washington.

Burns arrived in Turkey on Tuesday on a two-day visit to hold talks with the country's leadership on a range of issues, including Iran's controversial nuclear programme.
