Somali Islamist militant group al-Shabaab claimed responsibility for the attacks via a Twitter account. The spokesperson claimed the atrocity was in response to the presence of Kenyan troops in Somalia: "The attack at #WestgateMall is just a very tiny fraction of what Muslims in Somalia experience at the hands of Kenyan invaders," the account stated. "For long we have waged war against the Kenyans in our land, now it's time to shift the battleground and take the war to their land." It continued by saying that the Kenyan government was "pleading with our mujahideen inside the mall for negotiations. There will be no negotiations whatsoever.
Kenya has been braced for an attack of this kind since it controversially intervened in the war against al-Shabaab in Somalia by sending an expeditionary force in 2011. Since then Kenyan troops have succeeded in expelling the jihadists from the southern Somali port city of Kismayo and installing a former warlord friendly to the government in Nairobi.
Somalia's president – the leader of a country familiar with terrorist attacks – said his country knows "only too well the human costs of violence like this" as he extended prayers to those in Kenya.
"These heartless acts against defenceless civilians, including innocent children, are beyond the pale and cannot be tolerated. We stand shoulder to shoulder with Kenya in its time of grief for these lives lost and the many injured," President Hassan Sheikh Mohamud said.
