At least two hospitals in the Indian capital of Delhi are running out of oxygen, amid a healthcare crisis gripping several states in the country.
A number of people have died while waiting for oxygen supplies, and the majority of intensive care beds in Delhi hospitals are full.
India is in the grips of a second wave of Covid infections.
The country has close to 16 million confirmed infections and saw a record number of cases on Thursday.
Prime Minister Narendra Modi is due to hold meetings with state Chief Ministers of affected states and oxygen manufacturers on Friday.
In a tweet labelled “SOS” sent out on Friday morning, Max healthcare said it had been waiting for expected fresh supplies for more than seven hours at two hospitals.
It has 700 patients admitted at the two facilities. (BBC)
