Pakistani comedian Umer Sharif was shifted to the ICU of a private hospital after his health condition deteriorated on Sunday, hours before he was to leave for the US.

According to the details, his departure has been delayed after doctors said the next 48 hours are critical for his health.

Dr. Tariq Shahab, who is the husband of Pakistani actress Reema Khan is overseeing arrangements for Sharif’s treatment in the US, said to media that the actor’s blood pressure dropped at dialysis.
