A car bomb blast near a police station in Somalia's capital on Sunday killed at least five people and wounded at least 13 others, police said. The explosion shattered a month of relative calm in Mogadishu, often a target of the extremist group al-Shabab. The blast near Waberi police station along the busy Maka Almukarramah road may have been a suicide bomber, Capt. Mohamed Hussein told The Associated Press. The al-Qaida-linked al-Shabab often carries out deadly bombings in Mogadishu against high-profile targets such as hotels and checkpoints. Most of the victims Sunday were civilians. The exact target of the blast remained unclear. The blast occurred amid a traffic jam while soldiers were searching cars at a nearby intersection. Somalia's Prime Minister Hassan Ali Khaire said no such blast had occurred in the capital for a month. At the blast scene, rescue workers and civilians carried bloodied bodies and injured victims to hospitals. Burning vehicles outside Midnimo mall
