The CBI on Tuesday blamed Pakistan for not helping India in handing over wanted terrorists like underworld don Dawood Ibrahim saying it must honour several international and regional conventions in this regard.The CBI Director Vijay Shanker gave this assessment when asked for his reaction to awarding of life sentence to three persons - Abdul Latif, Dalip Bhujbal and Yusuf Nepali - for being a part of the conspiracy to hijack an Indian Airlines plane in December 1999.“Dawood Ibrahim is in Pakistan and we have taken up the matter with them directly. The five hijackers are there. Those who were released are very much on Pakistani soil. What else do they need,” Shanker told a press conference.Shanker also targeted the Federal Bureau of Investigation of the US saying they had also registered a case and received all kind of support from this investigating agency. “We have given them all the evidence but seems they are not interested,” he said.“What else proof does one need when one of the three released in exchange (Omar Sayeed Sheikh) is behind bars for killing Wall Street Journal scribe Daniel Pearl,” he said, adding there should be global cooperation in fighting terrorism.There is the Hague convention, Montreal Convention and even the SAARC convention of mutual assistance but none seems to be working for Pakistan, he said.Without naming anyone, the CBI Director said “countries should stop having double standards and rather work in close coordination with other international investigating agencies in fighting the scourge of terrorism."
