A presenter on a Kremlin-owned television channel is raising money to buy a water cannon, which he says he will use to attack London mayor Boris Johnson.
Keiser said the crowdfunding drive was a response to the Mayor's move to buy three of the cannons for the Metropolitan Police.
As of Thursday afternoon, 29 backers had pledged money to the project, amounting to a total of £207.
