Authorities in Venezuela denounced cyber attacks on the central hydroelectric plant which left 70% of the country without electricity

Electricity supply is being rapid restored in Venezuela after three days of power failure in 70% of the country as a result of the sabotage of a vital hydro-electric facility. Massive power outages began on March 7 following a cyber attack on the Simon Bolivar Hydroelectric Plant or the El Guri plant in Bolivar State. Telesur reported that as of 6 am local time, 40% of supply to Caracas was restored, with more and more suburbs regaining power in the following hours. The provinces of Aragua, Carabobo and Yaracuy to the north were still awaiting resumption of supply as of morning.
