Drupal 7 aggregator module with BBC persian feed
After you add new feed, make sure you update the items twice after removing them in the first time.

steps as follow:


add new feed
go to feed aggregator page admin/config/services/aggregator
update items manually by clicking on update items for the added feed
remove items by clicking on remove items for the updated feed
then update feed again update items


these steps worked for me while importing BBC persian and arabic feeds
