South Sudan is closing all schools from Monday in preparation for an extreme heatwave expected to last two weeks. The health and education ministries have advised parents to keep all children indoors as temperatures are expected to soar to 45C (113F). They added that any school found open during the warning period would have its registration withdrawn, but the statement issued late on Saturday did not specify how long schools would remain closed.
