A second wave of Covid-19 is devastating India, killing thousands of people each day and setting world records for daily infections.

Medical facilities have started to run out of oxygen, ventilators and beds in intensive care units. Workers are stretched thin.

Countries around the world are stepping up to offer aid as bodies pile up in morgues and crematoriums. Some authorities have been forced to hold mass cremations at makeshift sites.

"After successfully tackling the first wave, the nation's morale was high, it was confident," Prime Minister Narendra Modi said in his monthly radio program. "But this storm has shaken the nation."
