PARIS — The boss of Qatari television channel BeIn, Yousef Al-Obaidly, and ex-athletics chief Lamine Diack, have been under investigation since March over alleged corruption in the bidding process for this year's World Athletics Championships in Doha, sources told AFP on Tuesday.

Investigating magistrates are considering charging Al-Obaidly with active corruption, while Diack will act as a key witness in the matter and will be charged with passive corruption.

The championships take place at the Khalifa International Stadium between Sept. 27 and Oct. 6.

Earlier this week AFP learned that Diack and his son Papa Massata Diack may go on trial in a separate matter, for allegedly obstructing sanctions against Russia for doping in return for payments.

Prosecutors have recommended Diack, who was president of the International Association of Athletics Federations from 1999 to 2015, be tried for corruption and money laundering. — AFP
