An Israeli cyber group known on the Telegram messenger app as WeRedEvils claimed on Thursday that it managed to disable the electrical grid in Tehran, Iran, for two hours.

In addition, the group hinted that among those to lose power was Supreme Leader Ali Khamenei.

"In recent days, we managed to hack several sensitive systems in Iran, which we will not specify, among them the electricity grid in Tehran and the surrounding villages," they wrote.

They added: "We cut off their electricity, and we left tens of thousands of residents without a means of communication and electricity for two hours until this moment. This is a message from us to Iran: don't play with fire. The next strike will be harder with many more harmed, and it will be different from the cyber attacks that you're familiar with."

The group, which was created after the Swords of Iron War broke out, claimed that it managed to disrupt the operation of the Gazan Telegram channel "Gaza Now" after it shared videos from the massacre.

In addition, when the Hamas website fell, WeRedEvils claimed responsibility.
