Hackers say they crashed Abe's website to protest whale hunt

A hacking group said Thursday it has crashed Prime Minister Shinzo Abe’s official website to protest Japan’s plans to hunt whales.
Chief Cabinet Secretary Yoshihide Suga told reporters that one of Abe’s websites became inaccessible early Thursday and police were investigating. The site was restored by the evening.
Suga acknowledged that the Anonymous hacker group has posted a Twitter message claiming responsibility, but added authorities had not singled out the group as a prime suspect.
One of the group’s Twitter messages posted earlier Thursday criticized Japan over its whaling plans, and warned that Abe’s website would be brought down.
“@AbeShinzo whaling is not cultural right! Your website is #TangoDown!” the messages said. The group has also retweeted anti-whaling messages and one urging Abe not to eat whale meat and go vegan.

"responsibility"LDOCEで定義を確認すると"blame for something bad that happened"とありました。またclaim responsibility (for something)(＝say you are responsible)とも記載がありました。responsibilityは責任という意味ですが、ここではclaiming responsibilityとあり、自分の犯行を認めた声明を出したと明らかにしたことを指していると考えられます。(lua/kawada)
