MojNews-The head of the Russian National Security Council , Nikolai Patrushev said on Tuesday that Iranian defenses downed a U.S. spy drone last week while the aircraft was in Iranian airspace.

Speaking at the opening of a meeting in Jerusalem with his U.S. and Israeli counterparts John Bolton and Meir Ben-Shabbat , Patrushev said Russia had intelligence information that the U.S. drone had been inside Tehran&#۳۹;s airspace when it was shot down by Iranian defenses.

During his speech, Patrushev added that evidence provided by the U.S. allegedly implicating Iran in attacks on two oil tankers in the Gulf of Oman was "poor and unprofessional".
