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. https://www.bbc.co.uk/news/world-us-canada-48735097
