Central African Republic suffers food shortages as rebels cut off capital

State of emergency declared after armed opposition forces attack convoy carrying supplies and blockade the city of Bangui

Central African Republic is facing serious food shortages as election violence has cut off the country and stranded hundreds of trucks carrying supplies outside its borders.

Food prices have risen steeply since the landlocked country's main supply route from Cameroon was cut off by armed groups trying to blockade the capital, Bangui, where the government declared a state of emergency on Thursday.
