• The  death toll in attacks by gunmen in the Nigerian town of Mubi has reached 21, the Red Cross said on Saturday, and reports of fresh attacks on Christians in the country's northeast have heightened fears of a sectarian conflict.

  • Gunmen opened fire in a hall in Mubi on Friday where a group of Christians had gathered to mourn the deaths of those killed in an attack the previous day.

  • Mubi is in Adamawa state, just south of Borno state, the homeland of radical Islamist sect Boko Haram, whose members have been behind almost daily attacks in recent months.
