Ahead of their crucial World Cup semi-final against India, Pakistani cricketers have been warned not to indulge in any match-fixing by Interior Minister Rehman Malik who said he was keeping a "close watch" on their activities.

"I gave a warning that there should be no match-fixing. I am keeping a close watch. If any such thing happens, we are going to take action," Malik said two days ahead of the game in Mohali that will showcase one of the world's most intense sporting rivalries.
