New Delhi [India], May 1 (ANI): Delhi's World Brain Center Hospital, a designated COVID hospital, shut its operations temporarily on Friday due to the "shortage of oxygen".

"With utter disappointment, we have to shut down operations due to a shortage of oxygen. It is getting difficult to manage oxygen for our patients. To get one lot of oxygen it takes 18 to 30 hours for hospitals. We have serious patients who need continuous oxygen saturation," Dr Neelesh Tiwari, Director of World Brain Center Hospital said.
