The International Civil Aviation Organization says it has cautioned several European countries against refusing to supply Iranian passenger planes with fuel.
The ICAO said on Friday that it has raised the issue with authorities in Britain, Denmark, Germany, Sweden, and the Netherlands.
ICAO has also underscored that it will not remain silent on issues that undermine the safety of the aviation industry.
This came after Iran’s Civil Aviation Organization complained to the international body about the fuel sanctions by some European states against Iranian airlines.
