The Israeli government and security-related websites that crashed on Sunday began working once again overnight after long hours of malfunctions. The international hackers' group Anonymous had threatened the Israeli government in response to the Israel Navy's interception on Friday of two boats of activists trying to reach Gaza. Suspicions then arose that the group was responsible. Among the sites that were affected were those of the Israel Defense Forces, the Shin Bet security service and the Mossad, Israel's espionage agency. Israel's e-Government, responsible for managing the state's websites, denied claims that they were hacked.
