The United Kingdom and the European Union are sending ventilators, other medical equipment, and medicines to India.
British Health Secretary Matt Hancock called the scenes in India "heartbreaking" and said that the UK is "determined to support the people of India through this very difficult time."
The UK government said the first batch of its surplus ventilators and oxygen concentrator devices were due to leave the UK on Sunday and arrive in New Delhi early on Tuesday, with further shipments to follow within the week.
The statement said the government is working closely with the Indian government to identify the assistance the UK can provide in the coming days.
Prime Minister Boris Johnson pledged to work with the Indian government and make sure that "the UK does everything it can to support the international community."
The European Commission has also activated its EU Civil Protection Mechanism and is seeking to send oxygen and medicine to India.
"Alarmed by the epidemiological situation in India. We are ready to support," Commission President Ursula von der Leyen wrote on Twitter on Sunday.
"The EU executive is already coordinating with EU countries that are ready to provide urgently needed oxygen & medicine rapidly," European Commission for humanitarian aid Janez Lenarcic wrote on Twitter.
The number of COVID-19 daily cases and deaths has grown exponentially in India since late March. On Saturday alone, 349,313 new cases and 2,761 new deaths were recorded.
