Teams have long stayed away from Pakistan , concerned about the security situation in a country that is battling an escalating pro-Taliban insurgency . But Sri Lanka -- a country enduring its own civil war with separatist rebels -- agreed in December to visit for a series of matches , after the Indian cricket team called off its tour following the deadly terror attacks in Mumbai in November . Indian authorities blamed those attacks on Pakistan-based militants . The Pakistan Cricket Board had said it was set to lose more than $ 16 million as a result of India 's cancellation , but the Sri Lanka visit was to help it recoup most of the costs , officials said . The Sri Lankan offer to tour was a reciprocal gesture . Pakistan was one of two countries that agreed to tour Sri Lanka during the 1996 World Cup tournament , while other countries refused to travel there because of security concerns . With this attack , fans now worry that Pakistan wo n't be able to co-host the 2011 Cricket World Cup with India , Bangladesh and Sri Lanka . Morgan said the ICC 's board will be meeting in April to consider whether the Cup will include stops in Pakistan . `` The board will have to think very carefully about the extent to which Pakistan will be used for that event , '' Morgan said . `` It 's a very important event , but the safety and security of players , officials and supporters is very important and the board will be taking that into account .

He described the situation for the sport in the country as `` desperate . '' Watch how attack strikes at legitimacy of Pakistani government » .
