Zimbabweans returned to work after a week of strikes and violently repressed attempts at protests. But the country's daily suffering - including shortages of food, fuel, electricity, cash and even blood - is expected to bring a rapid return of tension. A five-day strike called last week by the Movement for Democratic Change was successful, but its attempt to bring people out on the streets "in your millions" was violently repressed by the security forces and their notorious militia allies, known as the "Green Bombers".
