Shekau appears in a new video

Boko Haram factional leader Abubakar Shekau has re-emerged in a
new video after a long absence that fuelled speculation about his health and ability to lead the Islamist militants.
In a 36-minute message, seen by AFP on Tuesday, Shekau wore a white robe and skull cap, and held an assault rifle as he sat in front of a military camouflage canvas.
He appeared unwell but made no direct mention of his health or reports from last month that he had high blood pressure, failing eyesight and diabetes-related complications.
