A man set off a tear gas canister inside the cardiac intensive care unit at Ain Shams University Hospital, also known as Demerdash, in the Cairo neighborhood of Abbasseya Tuesday morning, according to doctors at the hospital.
The perpetrator apparently set off the tear gas because he is in a fight with his wife, who is a nurse at the hospital, according to Mina Moussa, a doctor who works at the hospital.
Fire fighters controlled a small fire that erupted and the situation is now under control, eyewitnesses say.
Patients were moved to another unit and some are being treated for suffocation.
