Iran 'captures' US drone over Gulf waters "The unmanned US drone patrolling Persian Gulf waters, performing reconnaissance and gathering intel, was captured as soon as it entered Iranian airspace," the Revolutionary Guards said in a statement on Tuesday Iran is subject to US surveillance, notably over its controversial nuclear programme. Iran's foreign ministry said last week the United States had violated Iranian airspace eight times in October, and warned of a "serious reaction" if such incursions continued. On November 1, Iranian fighter jets fired on a US drone in the Gulf but failed to bring it down, according to ths US Defence Department. The most recent drone claim adds to military tensions between the two arch-foes in the Gulf. Iran said the aircraft was on a reconnaissance mission near Bushehr, which hosts its only nuclear power plant, as well as its main oil terminal at Kharg island. It said the drone had entered Iranian airspace.
