US 'launched cyber-attack on Iran weapons systems'

The US launched a cyber-attack on Iranian weapons systems on Thursday as President Trump pulled out of air strikes on the country, US reports say.

The cyber-attack disabled computer systems controlling rocket and missile launchers, the Washington Post said.

It 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, the New York Times said.

There is no independent confirmation of damage to Iranian systems.
