Zimbabwean state doctors entered the fifth day of a strike on Tuesday (18 July) that has crippled public health services and they have vowed to stay away from work until demands for better salaries and working conditions are met. Zimbabwe's health workers have staged a series of strikes in recent years to press for increases in salaries they said have failed to keep up with rising living costs amid an economic crisis widely blamed on President Robert Mugabe's 26-year rule.
