New Delhi, Aug 27 - Home Minister P. Chidambaram Thursday said he was 'puzzled' over a newspaper report stating that the country's second nuclear tests in Pokhran in 1998 had failed to get the desired yield.

'I have seen the report. I am puzzled. The government will find out, somebody will brief you,' Chidambaram told reporters after a meeting of the cabinet committee on economic affairs.

He was replying to questions about a report in The Times Of India daily Thursday that quotes a senior scientist associated with the 1998 tests as admitting that the only thermonuclear device tested was a 'fizzle.' A test is described as a fizzle when it fails to meet the desired yield.

The newspaper quotes K. Santhanam, who was a representative of the Defence Research and Development Organisation and a director for the 1998 test site preparations, who says the three tests were not such a big success as portrayed by the government.
