Libya flood: Derna mayor's house burnt down in protests

Hundreds of protesters in Derna , Libya , demand answers for last week's flooding.

Residents say they were not sufficiently warned by officials, who they believe must have known a huge amount of rainfall was coming.

UN now says one of its teams has been refused permission to enter the city.

More than 10,000 people are officially missing after two old and dilapidated dams burst.
