Indian-American billionaire Vinod Khosla has pledged $10 million for the supply of medical oxygen to hospitals in India.

Taking to Twitter the Sun Microsystems co-founder said on Sunday there was a need to save lives as further delay may end up in more deaths.

"The Khosla Family is adding $10 million to @GiveIndia to it's previous commitment as a match and hoping others will join in this urgent need," Khosla said.

"For @GiveIndia this isn't enough. They've received requests for 20,000 oxygen concentrators, 15,000 cylinders, 500 ICU beds, 100 ventilators, 10,000-beds COVID centres with requests coming from non-profits & hospitals all across India every day. We need to do a lot more urgently,"  Khosla said.
