A suicide bomber targeted a stadium in the central Somali city of Galkayo on Friday, killing 15 people, according to the police, shortly before the arrival of the country's new prime minister.

Ali Hassan, a Galkayo police officer, said others were injured in the explosion that took place at the entrance to the sports stadium. Some high-ranking members of the Somali army, according to local sources, were among those killed in the blast.

According to the group's Andalus radio station, the bombing was announced by Somali al-Shabab terrorists.

As part of a tour of the central state of Galmudug, Prime Minister Mohamed Hussein Roble, who took office in September, visited the city. Galkayo lies 466 miles north of the capital of Somalia.
