Israeli newspaper The Marker reported that a number of Israeli websites were down as a result of the cyber attack that targeted the occupation's ministry websites and shut them down on Monday evening.

The daily said that it is still unclear whether the attack was unusually widespread and dramatic, adding that it may still not be over yet.

Haaretz reported a security source as saying that this cyber attack was the most widespread against "Israel", despite it not being sophisticated, adding that "it is estimated that a large state or organization is behind the attack."

"Israel" Hayom said that the sites collapsed for long minutes, and were active again after the Israeli National Cyber System intervened.
