After a failure at the Guri hydroelectric power plant left much of the country without power on Thursday night, Venezuelan authorities managed to restore power to "many parts" of the country. However, the country's grid took another hammering on Saturday, with many of the restored systems knocked out once again, the country's embattled president said.

According to Maduro, the systems had been nearly 70 percent restored when "we received another attack, of a cybernetic nature, at midday… that disturbed the reconnection process and knocked out everything that had been achieved until noon."

We discovered that they were carrying out high-tech… attacks against the power systems.

Additionally, "one of the sources of generation that was working perfectly," was also sabotaged, he added, accusing domestic "infiltrators of attacking the electric company from the inside."

Authorities are now trying to restore the systems "manually," while struggling to "diagnose why the computerized" systems failed on such a massive scale.
