The family of the chairman of the electoral commission in The Gambia has told the BBC that he has gone into hiding.

There are reports that Alieu Momar Njai has fled the country because he received threats after declaring President Yahya Jammeh had lost the election.

Mr Jammeh initially admitted that he had lost the poll last month to his rival Adama Barrow, but then refused to step down.

Security forces took over the headquarters of the electoral commission shortly afterwards.
