IAAF vows to investigate new claims
The IAAF will look into fresh allegations of anti-doping rule violations in athletics made by German broadcaster ARD.
Fresh allegations surfaced via ARD on Sunday and the athletics governing body vowed to investigate.
"The IAAF thanks ARD and Mr. [Hajo] Seppelt for giving the independent chair Rune Andersen of the IAAF Taskforce advance access to video and audio recording material which was broadcast in today’s ARD/WDR documentaries," an IAAF statement read.
"The Taskforce will look carefully into the matters raised by the latest documentaries, including discussing them with representatives of RUSAF [All-Russia Athletic Federation]."
It remains unclear as to whether Russia will compete in athletics at the Rio Olympics.
