Two more people have died following a fire in a nightclub in Bucharest in Romania.

It brings the total number of victims from Friday's incident to 29.

Flames erupted after fireworks were let off during a heavy metal concert.

More than 100 people are still being treated in hospital, and officials say the number of deaths is likely to rise.

The fire unfolded at a Halloween party at the Colectiv club, and up to 400 young revellers were packed into the building's basement.

It is believed that pyrotechnics used during the concert inside the venue misfired because they were poorly fitted.

The spark ignited an acoustic pillar cased in polystyrene, causing fire to spread to the ceiling and the club to fill up with smoke.

There was only one emergency exit available, and many revellers did not immediately react because they thought the flames were part of the show.

Teenagers as young as 14 were inside the club when the fire began.

Prime Minister Victor Ponta cut short a visit to Mexico and flew home in light of the tragedy.

An investigation into the incident has begun, and the owner of the nightclub is helping police with their inquiries
