A huge fire has broken out at Dubai's Torch Tower - one of the tallest residential buildings in the world.
There are so far no reports of injuries.
Torch Tower, which is more than 80 storeys, previously caught fire in early 2015.
Fires have affected several skyscrapers in the United Arab Emirates including one that engulfed a 63-storey luxury hotel in Dubai on New Year's Eve in 2016.
Building and safety experts have cited a popular type of cladding covering the buildings that can be highly flammable.
One witness to Friday's fire said more than 40 floors of the high-rise tower appeared to be engulfed in flames on one side of the building.
