 To West Africa, at least 18 people have been killed and 30 injured in a series of deadly blasts in Nigeria's north-eastern Borno state, according to official authorities. The attacks took place at a wedding, a hospital and a funeral. So far, no group has claimed responsibility. Borno state has been at the centre of a 15-year insurgency by Boko Haram Islamist militants. The Nigerian journalist Idris Mohamed, who also worked as a researcher in terrorism in Goza, where the attacks happened, gave me this update.
