In September 2013 , Twitter suspended at least six al-Shabaab accounts after the outfit ridiculed the Kenyan government 's response to the Westgate shopping mall attack in Nairobi , an attack al-Shabaab claimed responsibility for . The group later re-opened a Twitter account in December , with the explanation that " the aim is to vigorously challenge defamatory reports in the media by presenting an accurate portrayal of the current state of Jihad in Somalia and countering Western , state-sponsored propaganda machines that are paid to demonise the Mujahideen . " A Somali government spokesman stated that the Somali authorities were opposed to al-Shabaab 's presence on the social media website , as the group " should not be given the platform to mislead the youth "
