Islamist group al Shabaab on Monday claimed responsibility for a bomb blast in Mogadishu that killed at least 90 people over the weekend while Somalia said a foreign government that it did not identify helped plan the attack.
The bombing was the deadliest in more than two years in a country wrecked by nearly three decades of Islamist violence and clan warfare.
In an audio message, al Qaeda-allied al Shabaab claimed responsibility for the bombing at the busy Ex-Control checkpoint northwest of Mogadishu.
"The blast targeted a convoy of Turkish and Somali forces and they suffered great loss," Ali Mohamud Rage, al Shabaab's spokesman said in the message.
