Security threats have had its toll on series before. And there are eight such previous instances to show; Sri Lanka and Pakistan being prominent on the list. Cases of terrorist threats have multiplied, and though the closest thing to an attack, so to say, has been the New Zealand’s 2002 trip to Pakistan, no cricket team or cricketer has really suffered injuries. The cricket community, though, remains wary of each and every situation that arises.Here is a list of such incidents:• New Zealand abandoned their tour of Sri Lanka in 1987 after a blast in Colombo’s Pettah region, killed 110 civilians and two policemen. The blast caused touring teams to avoid Sri Lanka for the next five years.• The same two teams again, with New Zealand returning home in 1993, following a suicide bomber attack outside the team’s hotel.• This was the bigger stage: Australia and West Indies forfeited their game in Sri Lanka citing security worries during the 1996 World Cup. • The West Indies-Pakistan Test and ODI series had to be shifted out of Pakistan to Sharjah in 2001. That was after the Caribbeans’ refusal to play in Pakistan, citing security reasons. • New Zealand’s tour to Pakistan in September, 2001 was cancelled over fear of retaliation on Afghanistan following terrorist attacks in the United States. • New Zealand again: they cancelled their tour of Pakistan midway after a suicide bomb attack outside the team hotel killed 11 people in Karachi in May 2002. • Then in 2002, Australia withdrew from a Test tour of Pakistan after the ACB raised serious security concerns following a tip-off from the Australian High Commission.• Australia pulled out of Morocco in 2003 after a series of blasts in Casablanca killed 43 persons.
