The Yemeni capital of Sanaa is at risk of losing its Old City district's status as a UNESCO world heritage site.
Sanaa's Old City was given the status in 1986, but UNESCO has recently threatened to take it away if the Yemeni authorities don't do more to prevent the destruction of old buildings in favor of new ones, made of concrete.
Now the Yemeni authorities are making efforts to defend the title.
