Moyes surprised by Hart's blunder
FIFA has charged World Cup hosts Russia over fan racism during their friendly against France, less than two months before the tournament begins.
Monkey chants were aimed at France players including midfielder Paul Pogba as France won in St. Petersburg last month.
"Disciplinary proceedings have been opened against the Russian Football Union for this incident," FIFA said on Tuesday.
The Russian Football Union (RFU) said it was cooperating with the FIFA investigation.
"A request has been made to the Interior Ministry to identify several persons who were involved in these incidents," RFU anti-discrimination officer Alexei Smertin was quoted as saying by the Tass news agency.
"If these people's guilt is proven, then there's a high likelihood they won't be allowed to attend World Cup and Russian league games."
It is the third racism case at St. Petersburg Stadium, which will host a World Cup semifinal match, this season. Zenit St. Petersburg have twice faced UEFA charges over racism by fans in Europa League games.
Russia was charged with racist behaviour by fans at the last two European Championships. On both occasions, the RFU paid a fine.
