India, China and Brazil walked out of the climate summit in Copenhagen on Friday, the Press Trust of India reported.

Indian Prime Minister Manmohan Singh, Chinese Premier Wen Jiabao and Brazilian President President Lula da Silva left the session to hold a parallel meeting, reportedly to confer about concerns over the "umbrella paragraph" in the draft of an agreement being worked on for signing later today.

The three reportedly later rejoined the conference.
