Iranian state TV Thursday showed the first video footage of an advanced U.S. drone downed by Iranian troops in the eastern region four days ago.
Images showed that Iranian military officials were inspecting the RQ-170 Sentinel stealth aircraft which appeared to be undamaged, BBC reported.
U.S. officials have acknowledged the loss of the unmanned plane, saying it had malfunctioned. However, Iran said its forces electronically hijacked the drone and steered it to the ground, according to the report.
"Recently, with the help of collected intelligence and with the accurate electronic monitoring, it was learned that the drone was to enter Iran's air space for spying," said the Islamic Revolution Guards Corps' (IRGC) Aerospace Commander Brigadier General Amir-Ali Hajizadeh, Xinhua reported.
"After the drone infiltrated Iran's eastern space, it was trapped by the electronic systems of Iran's armed forces and was downed with the least damage possible," Hajizadeh said.
He said Thursday that the military experts were well aware that the drone has very invaluable technological data.
The drone, the technology of which has been used in B2 and F35 planes too, was equipped with highly advanced surveillance technology and electronic communication and radar systems, he added.
The RQ-170 drone is an unmanned aircraft which has been used for reconnaissance and surveillance by the U.S. in Afghanistan.
The Iranian Foreign Ministry Thursday summoned Swiss Ambassador to Tehran Livia Leu Agosti to protest the violation of its airspace by a U.S. drone.
The Swiss embassy in Tehran represents the U.S. interests in Iran since Tehran and Washington severed diplomatic relations in 1980.
U.S. President Barack Obama Thursday said that no options were off the table on Iran's nuclear program.
"No options off the table means I'm considering all options," Obama told reporters at the White House.
While the West accuses Iran of developing nuclear weapons under the guise of "civilian" nuclear program, Iran insists that its nuclear program is only for "peaceful" purpose.
