text: The World Anti-Doping Agency (Wada) made its latest claims two days before Russia finds out whether it can send athletes to the 2016 Rio Olympics.
  They were banned from international competition after Wada accused Russia of state-sponsored doping.
  Athletics chiefs meet on Friday to decide whether to lift the ban.
  It says that:
  The report details the lengths athletes from different sports allegedly went to, both to avoid tests and fool doping control officers (DCOs).
  It says one athlete was seen running away from the mixed zone after an event, while another left the stadium during a race and could not be located.
  Wada also highlighted the case of an athlete who, it says, used a container - "presumably containing clean urine" - that had been inserted inside her.
  When she tried to use the container, it leaked onto the floor.
  The athlete is alleged to have tried to bribe the DCO before providing a sample that subsequently returned an adverse finding.
  The report also says that:
  As a result, tests were not carried out at the national weightlifting and national Greco-Roman wrestling championships.
  In some cases, testers were not told where an event was taking place.
  "What really comes through, when you read through it page by page by page, is the number of occasions when there was simply no co-operation given,"  former Wada president Dick Pound told the BBC World Service.
  The International Association of Athletics Federations (IAAF) voted to suspend Russia's athletics federation on 13 November after an independent Wada report alleged "state-sponsored doping".
  The report was commissioned to investigate claims made in a documentary shown by German broadcaster ARD in 2014.
  The programme alleged widespread doping in Russian athletics, claiming as many as 99% of athletes had cheated.
  The claims were made by whistleblowers, among them Vitaly Stepanov, a former Russian anti-doping official, and his wife Yulia, a former 800m runner who was banned for doping.
  Russian athletes, including former London Marathon winner Liliya Shobukhova, also admitted to taking drugs and observing corruption.
  The Wada report found evidence of state involvement, as well as evidence that samples had been destroyed, doping controls had been interfered and bribes had been paid to conceal positive tests.

  The IAAF meets on Friday in Vienna to discuss what Russian authorities have done to tackle doping and whether its athletes should compete in Rio.
  Russian sports minister Vitaly Mutko said the country could take legal action if its athletics federation was not reinstated, Interfax news agency has reported.
  "It is a big and an important message whatever is decided," said Pound.
  "If they are held to be excluded, that's a message. If they are allowed to come back in, there is going to be another message that all of the sporting authorities are going to have to deal with."
  Pound said a ban on Russian athletes competing in the Olympics would be extremely difficult for the Russian government to explain to its citizens.
  "You can explain all sorts of economic sanctions and political sanctions and what not if you are the state," he said.
  "But it is very hard to explain to a country that really enjoys its sport and likes to watch it why it is that nobody will play with you."
  Meanwhile, Russian Olympic medallists and world champions have appealed to the head of the International Olympic Committee to let athletes with no history of doping to compete at the Rio Games.
  "The fraud of dishonest people should not jeopardise the career of innocent fellow athletes," said 13 sports stars in a letter to Thomas Bach.
  The 13 include Alexander Popov, a four-time Olympic champion swimmer, and judo champion Tagir Khaibulaev.
  The Olympic athletics programme begins in Brazil on 12 August.
