A Kenyan court on Monday charged four Somali men with terrorist offenses for helping al-Qaeda-linked militants carry out the mall attack in Nairobi last month. The assault, claimed by the Somali Islamist group al Shabaab, killed 67 people. All the men were formally charged with "commission of a terrorist act" under Kenya's anti-terrorism laws, as well as a range of other accusations. The suspects all pleaded not guilty at the hearing. The men were named as Mohamed Ahmed Abdi, Liban Abdullah Omar and Hussein Hassan, while a fourth was identified as Adan Mohamed Ibrahim, although he was listed as using other aliases.
