Shehryar Khan, Chairman of Pakistan Cricket Board(PCB), on Friday, the inconclusive inquiry into the 2008 Mumbai attacks was a major hurdle in the reviving sporting ties between the arch-rivals. India stalled all bilateral ties in the wake of the attacks on India’s commercial hub.I that attack 166 people were dead and the blame was on Pakistan-based militants.

The Board of Control for Cricket in India (BCCI) and its counterpart The Pakistan Cricket Board (PCB) have signed an agreement which says that the two team, India and Pakistan will play six series in the next eight years, the first to be hosted by Pakistan in December 2015. But these series are still awaits of New Delhi’s clearance.

Lahore Lions, domestic team of Pakistan are also due to feature in the Champions League Twenty20 event in India from September 13 but reports suggest their participation remains doubtful amid recent border tensions. PCB chairman Shaharyar Khan said that Mumbai remained the key hurdle.

He told reporters that “We usually have tension on the border but the real thing is that their public is against us because of the Mumbai attacks, they say that there is no progress on the investigation. Until and unless the case is closed the ties will remain affected.”

Pakistan indicted seven people over the Mumbai attacks but their trial, which began in 2009, has made little headway, prompting Indian accusations that the process was a sham. But Khan played down doubts over Lahore Lions’ participation in the CL as “rumours”.

Khan, a former diplomat who was born in Bhopal in the undivided India in 1934, said he would resume talks with BCCI and Indian government officials. ”I will go to India soon and will also meet their officials on the sidelines of the ICC (International Cricket Council) meeting in Dubai and I have good relations with all of them in India,” he said.

Pakistan team toured India for a two Twenty20 and three one-day international match series but that failed to resume the full ties. India’s last full bilateral tour to Pakistan was in 2006.
