NEW DELHI, India (AFP) — Indian cricketers Yuvraj Singh and Harbhajan Singh have unleashed a social media storm by backing former Pakistan captain Shahid Afridi’s foundation in its fight against the coronavirus pandemic.

The two countries are bitter rivals and the move touched a raw nerve in India.

Afridi’s appeal for donations to help people affected by the deadly virus in Pakistan has had overwhelming support from leading cricketers.

Harbhajan urged people to contribute in a video message, and called on other cricketers in the two countries to make similar appeals.

“These are testing times, it’s time to look out for each other,” Yuvraj wrote on Twitter in a call for funds.

While Afridi thanked the two, Indian Twitter users reacted with fury at the support for a rival player who has been a vocal critic of India’s handling of the Kashmir dispute.

“Do you have any sense?” wrote one Twitter user. “Lost respect” for Harbhajan Singh, added another. “Sorry guys you lost it.”

World Cup-winning batsman Yuvraj, who made a return from cancer before finally retiring last year, hit back at his trolls with a message.

“I really don’t understand how a message to help the most vulnerable gets blown out of proportion!,” he wrote. “ I’m an Indian and will always bleed blue and will always stand for humanity.”

India and Pakistan have not played a bilateral cricket series since 2012-2013 and have seen a new peak in tensions over Kashmir, which has been at the centre of two wars between the neighbours since 1947.

Kashmir has been divided between the two since their independence seven decades ago and India frequently accuses Pakistan of organising “terrorism” on its side of the border.

The 38-year-old Yuvraj has also raised money to fight coronavirus through his ‘YouWeCan’ foundation.

India, which has been under a 21-day lockdown since March 24, has so far confirmed more than 1,600 coronavirus cases and 38 deaths.
