What percentage of students is staying away from school in Zimbabwe in 2008?

The UN Children’s Fund reports school attendance in Zimbabwe has rapidly declined from more than 85 percent in 2007 to just 20 percent by the third term of 2008. The UNICEF Representative in Zimbabwe, Roeland Monasch, says the cholera epidemic and the collapse of basic services are adversely affecting the population. He says children are staying away from school because they have to help their parents look for food or find ways to earn money to help support their families.
Q: What percentage of students is staying away from school in Zimbabwe in 2008?

It was a tense standoff that lasted more than twenty four hours—this quiet farming town suddenly at the centre of what many described simply as a nightmare. It began when four gunmen entered the bank intending to make a quick getaway. When they spotted a police patrol, they panicked and so began the siege—more than thirty people held hostage. As the hold-up continued, some managed to make calls and send texts to friends and relatives. Others stuck hastily written notes in the windows pleading for help. The gunmen were demanding money and a guaranteed escape. At first authorities refused but finally a deal was struck and the robbers fled the building in an ambulance, taking with them five hostages. The others were then able to leave. They emerged looking emotional, clearly relieved to be free. But the drama was not yet over. Police had promised the gunmen that they wouldn’ t be followed but several hours later they were stopped on a highway and surrounded. The men released their remaining captives, threw down their weapons and surrendered: a tense ordeal ending without a shot.
