Rio de Janeiro has opened the Paralympic Games with samba, parading wheelchairs, giant balloons – and loud booing of Brazil’s president – at a sold-out Maracana stadium.

The extraordinary sight of US Paralympian Aaron Wheelz jumping in his wheelchair from a 17-metre ramp got the crowd on its feet.

Then the joyous rhythms of samba singers and a carnivalesque reproduction of a Rio beach scene got them dancing.

But Brazil’s tensions also flared with thousands in the crowd chanting “Out with Temer!” as newly sworn in President Michel Temer appeared at the ceremony just days after taking over from bitter rival Dilma Rousseff, who was impeached.

Temer’s hurried declaration of “I declare the Games open” met a roar of boos, while booing forced Brazilian Olympics boss Carlos Nuzman to pause his speech after he mentioned “thanks to the federal, state and municipal governments”.

For Rio, the Paralympics, coming right after a vibrant but sometimes tricky Olympics, are one more challenge in a period of deep recession and political instability.

But Nuzman said “Brazilians never give up,” then he told the athletes: “You are superhumans.”

Blind, missing limbs, or partially paralysed, more than 4300 of the world’s toughest and most competitive disabled paraded ahead of 11 days of contests. Some pushed their own wheelchairs, others were pushed, while others limped.

When the Brazilian team came out in flower-patterned jackets, led by a storming contingent of athletes in wheelchairs, the legendary football stadium roared in delirium.

Aussies led by Ness

Ness is in his fifth Games, looking to add to a gold from Beijing and two silvers in Athens and London.

Not all of the 177-strong Australian team were present for the ceremony, with many watching back in the athletes’ village.

The team is looking to improve on its performance in London, where the Australians came fifth on the table with 85 medals, including 32 gold.

Controversy hung over the no-show by International Olympic Committee (IOC) president Thomas Bach – the first absence of an IOC chief since the 1984 Summer Games.

Bach is due at a mourning ceremony in Berlin for the late West German president Walter Scheel.

There have been suggestions that the no-show has to do with divisions over the Paralympic committee’s outright ban on Russian athletes after allegations of a state-sanctioned doping program and the IOC’s relatively softer line.

There were also reports in Globo and other Brazilian media outlets that Bach is wanted for questioning by local police investigating an illegal ticket selling ring allegedly involving a senior Irish Olympic official. Rio police were to give a press conference on the matter on Thursday.

Caught in political and economic crises, Rio 2016 organisers have skimped as far as they can on food, transport and accommodation.

The run-up to the Games was also overshadowed by slow ticket sales. This follows concerns about half-empty stadiums at many of the Olympics events.

But organisers have reported a dramatic turnaround in the last few days.

“Two weeks ago we were at 200,000 tickets sold,” said Sir Philip Craven, the International Paralympic Committee president.

Now sales have reached 1.6 million and are “growing every day”.

“We’ll soon be over the 1.7 million mark. Our aim is to sell around 2.4 million,” Craven said.

New stars set to emerge

Six countries are sending athletes for the very first time, and Syrian swimmer Ibrahim Al-Hussein, who lost a leg in an explosion in his nation’s civil war, and Iranian discus thrower Shahrad Nasajpour make up a two-strong refugee team.

The record of 41 career gold medals won by blind American swimmer Trischa Zorn between 1980 and 2004 looks unbeatable, but the Paralympics will inevitably produce new stars.

Iran’s 28-year-old powerlifter Siamand Rahman, disabled since birth, is aiming to become the first Paralympian to bench press 300 kilograms. Others to watch include Britain’s wheelchair racer David Weir and China’s blind sprinter Liu Cuiqing.

China will have its biggest ever team of 308 athletes in Rio looking to beat its 95 gold medals from London when it topped the table for the third straight Paralympics.

It has swimmer Xu Qing competing in his fourth and possibly last Games, seeking to add to his seven gold medals.
