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.
The National Intelligence and Security Agency did not name the country that it said was involved in the blast. “A foreign country planned the massacre of the Somalis in Mogadishu on 28 Dec 2019,” it said in a tweet.
