Iran warned the United States on Thursday against violation of its borders, with parliament speaker Ali Larijani threatening a stronger reaction, a week after Tehran shot down an American drone that spiked tension between the countries.
"The downing of their drone was a good experience for them to avoid any aggression against our borders," the semi-official Tasnim news agency quoted Larijani as saying. "Iran's reaction will be stronger if they repeat their mistake of violating our borders."
