Washington: The United States launched cyber attacks against Iranian missile control systems and a spy network this week after Tehran downed an American surveillance drone, USA media reported on Saturday.
Tehran insists that the drone violated its airspace - something Washington denies - but it was prepared to accept on Friday that it might have done so by accident.
Joneidi further denounced the USA move to deploy a spy drone into Iranian airspace as a "violation of the global law", noting that Tehran will be taking judicial measures in this regard.
"No one has granted them a hunting licence in the Middle East", he added.
Pence told the CNN television network, "Iran must not take restraint for a lack of resolve". "Our decisions hinge on their decisions and we will counter any aggression whether it mingles with threats or not". 'Sanctions are biting, and more were added last night.
"Sanctions are biting", he said.
"We're not going to have Iran have a nuclear weapon", Trump told reporters outside the White House.
After the drone was downed, Trump secretly authorised US Cyber Command to carry out a retaliatory cyber attack on Iran, The Washington Post reported Saturday.
Trump later said he had called off a military airstrike to retaliate because it would've killed 150 people. "10 minutes before the strike I stopped it", Trump tweeted, saying the action would have been disproportionate.
The cyber-attack targeted weapons systems used by Iran's Islamic Revolutionary Guard Corps (IRGC), which shot down the U.S. drone.
A spokeswoman said: "The UK has an ongoing diplomatic dialogue with Iran".
World powers have called for calm after the incidents. "That is what we are working on", she told Reuters.
Britain said its Minister of State for the Middle East Andrew Murrison would travel on Sunday to Tehran for talks. Iran is now facing strong economic pressure after the United States withdrew from the Iran Nuclear Deal in 2018 and reimposed stringent sanctions against the Islamic country.
Hanegbi predicted, however, that Washington could still hit out at the Iranians if provoked in the Gulf.
"If the leadership of Iran behaves badly, then it's going to be a very, very bad day for them", he said.
For his part, Trump says he will be Iran's "best friend" and that the Islamic Republic could be a "rich" country if it renounces nuclear weapons.
"Not as far as I'm concerned", the president replied.
