Truck bombs in Somalia's capital city, Mogadishu, killed more than 320 and injured hundreds earlier this month. The Somali government has said the militant group al-Shabab was behind the bombing -- the country's deadliest terrorist attack. 

Mohamed Nur of Denver had friends and family in Mogadishu at the time of the attack. Nur told Colorado Matters he first learned about the bombing from friends who posted photos on Facebook. Now, he says, the city needs "medicine and moral support."

Nur fled Somalia nearly 30 years ago to escape violence and civil war. Today he runs his own limousine service and is president of the Somali American Culture Center of Colorado.
