A bombing at a checkpoint in Somalia has killed at least 15 people and wounded 40 others, authorities have said.
Images on social media showed a damaged truck cab on fire and black smoke billowing from the scene in the central city of Beledweyne.
No one has immediately claimed responsibility, including Al Shabaab, which often carries out attacks and controls parts of Somalia.
Police officer Ahmed Aden said the dead included five police officers who fired on the truck in a failed attempt to stop it from ramming into the nearby checkpoint.
Shops nearby were reduced to rubble, with reports of people missing beneath the debris.
It was a truck loaded with explosive devices that forcefully passed through the government-manned checkpoint, and a pick-up vehicle belonging to security personnel was chasing it when it exploded,” said witness Abdikadir Arba, who said he was about 200 metres away and was one of the first responders.
Abdifatah Mohamed Yusuf, director-general of the Hirshabelle Ministry of Humanitarian and Disaster Management, confirmed the deaths.
“Twenty of the wounded have been admitted to Beledweyne hospitals, while another 20 are in critical condition, prompting a request for their airlift to Mogadishu for advanced medical treatment,” he said.
Hirshabelle is a state that includes Beledweyne. It has been the centre of the Somali government’s latest military offensive against extremists from Al Shabaab.
Al Shabaab has been battling Somalia’s central government for more than a decade, aiming to establish its rule based on strict interpretation of Islamic sharia law.
