The number of deaths at Jabalia refugee camp following the fire - which is now under control - is likely to rise, Salah Abu Laila, director of emergency services at the Indonesian Hospital in north Gaza, told BBC.

A local security official told the BBC an initial investigation suggested there was a gas leak from a kitchen.

Gaza houses eight refugee camps and one among them is Jabalia.

Abu Laila described the fire as "huge", with videos on social media showing the entire building engulfed in flames.

A local eye witness said gasoline was stored in the building 'to operate generator'.

An eyewitness told the BBC: "It is very difficult, children and women burning without the possibility of saving them."
