The National:

US Democratic Senator Elizabeth Warren has officially launched her bid for the 2020 presidency with a call to fight economic inequality and build “an America that works for everyone”.

Warren delivered a sharp call for change at her presidential kick-off, decrying a “middle-class squeeze” that has left Americans with “too little accountability for the rich, too little opportunity for everyone else”.

The 69-year-old and her backers hope that message can distinguish her in a crowded Democratic field and help her move past the controversy surrounding her past claims to Native American heritage.

Weaving specific policy prescriptions into her remarks, from universal healthcare to the elimination of Washington “lobbying as we know it”, Warren did not hold back in her criticism of President Donald Trump.

The former Harvard law professor also urged voters to choose “a government that makes different choices, choices that reflect our values”.

The National: Marilia Barros da Silva, grieves over the coffin containing the remains of her son, the young soccer player Arthur Vinicius, one of the victims of a fire at a Brazilian football academyMarilia Barros da Silva, grieves over the coffin containing the remains of her son, the young soccer player Arthur Vinicius, one of the victims of a fire at a Brazilian football academy

ELSEWHERE, football club Flamengo in Brazil has defended its management of the training ground where a fire killed 10 of its academy players.

Rio de Janeiro’s city hall said in a statement that Flamengo was fined 31 times because of infractions at the Ninho do Urubu training ground, which had to be temporarily closed in October 2017. The club did not pay 21 of those fines.

City hall also said the sleeping quarters where Flamengo’s players – all aged between 14 and 16 years old – died was irregularly licensed as a car park. Three teenagers injured in the fire were still in hospital, including one in serious condition.

Flamengo’s chief executive Reinaldo Belotti insisted the licensing issues “have nothing to do with the accident”.

He said the sleeping quarter was a proper lodging and not an improvised structure.

Belotti linked heavy rains to what he called “a tragic accident” and said unstable electricity may have sparked the fatal blaze.

AND finally, Five watercolours attributed to Adolf Hitler have failed to sell at auction in Germany.

The paintings, from his early days as a struggling artist, failed to sell in Nuremberg, possibly over fears they could be fakes.

The Nuremberger Nachrichten newspaper reported that no bids were received on the paintings, which had starting prices of between €19,000 (£16,600) and €45,000 (£39,300).

Three days before Saturday’s auction, prosecutors seized 63 other paintings attributed to Hitler from the auction house to investigate allegations they were fakes. Three other Hitler watercolours were seized in Berlin last month after their authenticity was questioned.
