The United States of America has launched a cyber-attack on Iranian weapons systems as President Donald Trump pulled out of air strikes on the country, BBC reports.
The cyber-attack disabled computer systems controlling rocket and missile launchers, the report added.
According to further reports, the action by the US was in retaliation for the shooting down of a US drone as well as attacks on oil tankers that the US has blamed Iran for in the past.
The US has also imposed sanctions President Trump described as “major”.
Trump said the sanctions were needed to prevent Iran from obtaining nuclear weapons, and economic pressure would be maintained unless Tehran changed course.
Tensions between the US and Iran have risen since the US last year pulled out of a 2015 nuclear deal Iran and world powers, and reinstated sanctions, triggering economic meltdown in Iran.
Last week Iran said it would exceed internationally agreed limits on its nuclear programme.
Mr Trump has said he does not want war with Iran, but warned it would face “obliteration” if conflict broke out.
