Nearly 300 people are missing after a Dam collapsed at an Iron Ore mine in south-eastern Brazil, officials say.

The Break caused a sea of muddy sludge that buried The Dam 's cafeteria where workers were eating lunch on Friday.

Rescue teams used earth-moving machinery at The Site near The Town of Brumadinho, in Minas Gerais state.

State governor Romeu Zema said there was little chance of finding people alive. So far 11 people have been confirmed dead.

It is not clear what caused the collapse of The Dam , owned by Brazil's largest mining company, Vale.

On Saturday, President Jair Bolsonaro flew over the disaster area in a helicopter. He tweeted that it was hard not to get "emotional" after seeing the scale of the Devastation .

President Jair Bolsonaro said all efforts were being made to rescue survivors

He said he had accepted an offer by Israel to send search equipment that could find people buried in the mud.

Also on Saturday, Brazil's Environmental Protection Agency (Ibama) issued Vale with an initial fine of 250m reais ($66. 5m; £50m) in relation to The Incident .

Meanwhile a sum of 5bn reais has been frozen from Vale's accounts by a court to help fund recovery works and handle damage claims.

The collapse comes just over three years since a Dam Burst in Mariana, also in Minas Gerais, killing 19 people, in what is considered.

What do we know about the collapse?

The Torrent of sludge cut through The Dam 's complex, nearby farms and The Neighbourhood where many of the workers live, destroying houses and vehicles.

There are reports that The Dam 's alarm System - which local residents had been trained to respond to - failed at the time of The Accident .

But Vale President Fabio Schvartsman said The Accident may have occurred too quickly for a siren which triggers security protocols to be activated.

The Globo website later reported that rescue officials provided The Following breakdown on The Number of The Missing :

The Dam is owned by Brazil's largest mining company, Vale Hopes are fading for survivors The powerful current swept everything in its way

Built in 1976, The Dam was one of several in the area and it was used to hold residue from The Mine .

It had capacity for 12m cubic metres and had been an inactive site for three years, Vale said.

What has the reaction been?

Mr Schvartsman called it a "human tragedy" and said a German company, hired to assess The Dam , indicated in The Most recent report last September that it was stable.

The Firm said it was monitoring all its other dams.

A report by Folha de S. Paulo newspaper said The Last month (in Portuguese).

Roads have been destroyed by the sludge, complicating rescue efforts

The environmental activist group Greenpeace said The Dam break was "a sad consequence of the lessons not learned by the Brazilian Government and the mining companies. "

It said the incidents "are not accidents but environmental crimes that must be investigated, punished and repaired".

What happened in 2015?

On 5 November 2015, a Dam - also owned by Vale, along with BHP Billiton - Burst at a Samarco mine in Mariana.

More Than 60m cubic metres - Enough to fill 20,000 Olympic swimming pools - spilled over into the surrounding area.

After a lengthy court case, BHP Billiton and Vale reached a settlement worth at least 6. 8bn reais with the Brazilian Government .
