Iranian Foreign Minister Mohammad Javad Zarif said on Thursday that Iran has recovered debris of the downed US drone in the country's southern waters, Iranian Student News Agency (ISNA) reported.

"We have gathered the debris of the US military drone in our territorial waters, where it was downed," Zarif was quoted as saying.

Earlier in the day, Iran's Islamic Revolution Guards Corps announced that its air force downed "a US RQ-4 Global Hawk spy drone" when it entered Iran's airspace near Mobarak Mountain region in the southern coastal province of Hormozgan.
