TEHRAN - Sanctions against Iran that have made it more difficult for its passenger planes to refuel abroad are "inhuman" and will be countered, Tehran's Foreign Ministry spokesman said on Tuesday."Not supplying a passenger plane with fuel is an inhuman action that violates international norms," Ramin Mehmanparast told his weekly news conference."We have informed the relevant authorities and if a country is acting contrary to the principles, avoiding supplying fuel, we will counter it and take necessary measures."
