Iran's Foreign Minister Javad Zarif has confirmed reports of President Hassan Rowhani's well-wishes on Jewish new year on social networking platform Twitter on Thursday. CNN's Christiane Amanpour posted a message on Facebook stating that she had just spoken to the Iranian foreign minister who confirmed to her Rowhani' tweets. “Just spoke with Iran's foreign minister who confirms he IS tweeting and wishes Jews in Iran & around the world a happy new year!,” Amanpour wrote in a tweet.

The Syrian Electronic Army, a hacker group that has previously attacked media organisations that it considers hostile to the government of Syrian president Bashar al-Assad, claimed credit for the Twitter and Huffington Post hacks in a series of Twitter messages late on Tuesday.

Last week, it was brought to a lot of people's attention that al Qaeda were active on Twitter. This was slightly less surprising than it sounds. At a grassroots level, these early masters of the viral beheading video know social media's black magic well enough, which is probably why they decided to crowdsource ideas of how they could improve their online image.

#you_tried. A jihadist Twitter account tried to solicit suggestions from the al Qaeda community Wednesday by creating the hashtag #اقتراحك_لتطوير_الإعلام_الجهادي, which roughly translates to #Suggestions_to_develop_Jihadist_media, according to a linguist fluent in Arabic who translated it for Business Insider.
