The RFEF said it had fined the Mali striker an unspecified amount. But the BBC reported that other reports suggest the fine for Kanoute is somewhere in the region of US$4,000.
The forward displayed a black T-shirt on which the word "Palestine" was printed in several languages. Kanoute, who was born in France but plays internationally for Mali, is a practicing Muslim, the report added.
Kanoute's action, which has been interpreted as a response to Israel's recent attacks on Gaza that have killed over 700 people, was met with a yellow card from referee Antonio Mateu Lahoz.
Lahoz said in his post-match report that he'd cautioned Kanoute for raising his shirt over his head in accordance with federation rules, while also noting the message of the striker's T-shirt.
