Pakistan's cricket chief flew to India Thursday in a last-ditch bid to rescue the series between the two nations, in doubt following the Mumbai attacks. India are due to tour Pakistan early next year, but strained political relations after New Delhi blamed the deadly siege on elements based here mean the series is now unlikely to go ahead. Pakistan Cricket Board (PCB) chief Ijaz Butt will meet Indian cricket officials on the sidelines of an Asian Cricket Council meeting on Friday to try to rescue the tour, the Board said. "The PCB chairman is off to India and on the sidelines of the ACC meeting he will have one-to-one talks with BCCI officials and try to ensure the series is played on schedule," chief operating officer Salim Altaf told a foreign news agency.
