WATCH: Israeli prime minister released from hospital

Israeli Prime Minister Benjamin Netanyahu was discharged from the hospital shortly after midnight on Wednesday, after undergoing medical tests.

A statement released by the prime minister’s office said the reason for Netanyahu’s short-term hospitalization was “high fever and cough” and that tests show he suffers from a “minor viral infections of his upper respiratory tract.” The doctors, the statement continues, “recommended rest and medication.”

The hospitalization followed the Israeli leader's coming down with a throat infection in mid-March after returning from a trip to Washington, D.C. He kept his usual schedule despite the infection, and Netanyahu's personal physician, Dr. Zvi Herman Berkowitz, said he suspected the prime minister had not gotten the rest needed for a full recovery which worsened the symptoms.
