Extremists set off a bomb in a U.N. van in normally tranquil northern Somalia on Monday, killing at least seven people, including four employees of the U.N. children's agency in an attack that was widely denounced. Two Kenyans, one Ugandan, one Afghan and three Somalis died in the explosion in Garowe town and one American, one Sierra Leonean, one Ugandan, one Kenyan and four Somalis were wounded, police Col. Ali Salad told The Associated Press. Somali President Hassan Sheikh Mohamud called it a direct attack on the future of the country, AP reported. -- SPA 19:44 LOCAL TIME 16:44 GMT تغريد
