Russia said on Tuesday it had paid millions of dollars to reward the people who helped it find and kill Chechen rebel leader Aslan Maskhadov, as an outcry grew over Moscow’s refusal to return his body for burial.

Maskhadov was killed a week ago in what troops said was a targeted raid, but Russian and foreign media raised questions over the manner of the veteran rebel’s death and activists have slammed the decision to bury him in an unmarked grave.
