Question: How many games were won in the 2009 CECAFA Cup by the team that Eritrea beat 3-1? Passage:Eritrea returned to the 2009 CECAFA Cup in Nairobi. A young squad was assembled with just 12 days' training. In Group B, they gained a surprise draw with Zimbabwe, lost narrowly to Rwanda, and beat Somalia 3–1. They were easily beaten 4–0 in the quarter-finals by Tanzania. Twelve squad members failed to report for the return flight, and sought the assistance of the Refugee Consortium of Kenya. They were believed to be in hiding in Eastleigh, an eastern suburb of Nairobi home to many immigrants. Nicholas Musonye, the secretary-general of CECAFA, feared that the government might react by refusing to let the team travel abroad in future. The twelve players were later granted interim asylum by the United Nations High Commissioner for Refugees in Kenya. Eleven of these players have since travelled to Adelaide in Australia with two of them, Samuel Ghebrehiwet and Ambes Sium, signing for Gold Coast United in the A-League in August 2011.
