The kidnap of more than 100 girls from a boarding school in north-eastern Nigeria has become shrouded in confusion.
We know that a group of militants, presumably from Boko Haram, arrived in the town of Dapchi, Yobe State, during the evening of Monday, 19 February.
They headed for the Government Girls Science and Technical College, fleeing a little while later.
Originally, it was claimed many of the girls had escaped and no-one had been kidnapped. But a week later, authorities have admitted they were taken by the Islamist extremists.
So, what exactly is going on?
