Covid-19: South Africa halts AstraZeneca vaccinations

Also, delayed elections leave Somalia facing a power vacuum after President Mohamed Abdullahi Mohamed's term expired with no clear succession plan. And in Sudan, new violence revives old fears. Many displaced people have started returning to their homes in Darfur, but recent attacks in the region have led them to question their choice.
