And have a read of this. Its not just NZ/Australia/England that have these concerns...
POTCHEFSTROOM, South Africa, Feb 1 AAP - South African veteran Gary Kirsten has admitted he would refuse to play in Zimbabwe if his side was due to visit the strife-torn nation during the World Cup.
Kirsten's revelation comes on the back of reports of an Al-Qaeda cell planning to attack Westerners in Zimbabwe - and South Africa - if the US goes to war with Iraq.
Kirsten, whose side is not drawn to play any matches in either Zimbabwe or another trouble spot, Kenya, told a charity function he believed there was a "security issue" around matches in Zimbabawe.
"Politics should be left to the politicians," said Kirsten.
"But I would not play in Zimbabwe... there is a security issue."
