A suicide car bomb attack on a government security base in Mogadishu Monday killed at least six policemen and wounded scores of others, a police official told AFP. "At least six police officers were killed. Many others were wounded, the toll could be higher but I don't have more details," said Abdirahman Issa, a senior police official in the Somali capital. He added a number of civilians in the area were also believed to have died in the explosion.
