And Russia demands evidence

 MOSCOW—Russia defended itself on Tuesday against accusations of a deeply rooted culture of state-sponsored doping in track and field, even as the head of its antidoping laboratory resigned in the wake of a searing report by the World Anti-Doping Agency.
Kremlin spokesman Dmitry Peskovsuggested that the detailed 323-page report, released by a WADA commission tasked with investigating allegations of widespread doping in Russian track and field, offered insufficient proof.
“If particular allegations are going to be aired, then they should be backed by particular evidence,” Mr. Peskov told Russian journalists. “So long as they haven’t presented the particular evidence, it’s hard to accept the particular allegations. They remain unfounded.”
 It wasn’t immediately clear what Mr. Peskov and other Russian officials meant by a lack of evidence in the WADA commission’s report.
