A television channel has said it has caught on camera international umpires agreeing to fix matches during domestic Twenty20 tournaments.
Footage screened on India TV on Monday showed umpires from Pakistan, Bangladesh and Sri Lanka negotiating deals with under-cover reporters to spot-fix matches.

The channel showed footage of Pakistan's Nadeem Ghauri, Nadir Shah of Bangladesh, part of the International Cricket Council's (ICC) international panel of umpires, and Sagara Gallage of Sri Lanka agreeing to give favourable decisions in exchange for umpiring contracts and money.
The ICC said in a statement: "The ICC and its relevant members have been made aware of the allegations made by India TV this evening and calls on the station to turnover any information which can assist the ICC's urgent investigations into this matter.
"The ICC re-iterates its zero-tolerance towards corruption whether alleged against players or officials. The ICC confirms that none of the umpires named were involved in any of the official games of the ICC World Twenty20 in Sri Lanka."
The World Twenty20 tournament ended on Sunday.
