A military coup in Mauritania brings opposition supporters out in celebration, and puts the country's democratically elected leaders in jail.

Mauritania, in the north-west of Africa, has been gripped by political uncertainty since its government faced a no-confidence vote last month.

The president and other key leaders are being held by the army. The head of Mauritania's presidential guard has declared himself in charge.
