Qatar has arrested 10 people on suspicion of spying for Iran’s Revolutionary Guards, according to the Qatar News Agency.
The report said seven of those detained were assigned to gather intelligence on “important and military installations,” while three were allegedly involved in planned sabotage operations.
During interrogation, the suspects reportedly confessed to being affiliated with the Revolutionary Guards and to receiving espionage and sabotage assignments.
Officials said maps of sensitive locations, coordinates, communication devices and other technical equipment were recovered from the suspects.
The arrests come as Iran has launched retaliatory attacks on Qatar and other Gulf Arab states since Saturday, following joint US-Israeli operations.
Iran says it is targeting US interests in the region, though reports indicate that civilian facilities, including airports and hotels, have also been damaged.
Dozens of explosions have been reported in Qatar in recent days.
The Qatari Defence Ministry said three cruise missiles, 101 ballistic missiles and 39 drones were launched towards its airspace since Saturday, all of which were intercepted and destroyed by air defence systems.
The Foreign Ministry said Iran did not inform Doha before the attacks, describing them as unexpected.
Spokesman Majid Al-Ansari said an attempt was made to target Hamad International Airport, but all missiles were intercepted.
He added that around 8,000 people are currently stranded in Qatar due to airspace closures.
Meanwhile, Oman, which had been mediating talks between Iran and the United States before the conflict, called for a ceasefire on Tuesday.
Omani Foreign Minister Badr Al-Busaid said diplomacy could help reduce tensions.
