Rabbi Ovadia Yosef, the spiritual leader of the Shas movement, collapsed Saturday morning during the Shacharit prayer in the synagogue under his home in Jerusalem.

A Red Magen David ambulance took him from the synagogue to Hadassah Ein Kerem hospital. His condition was defined as good.

The Director of Hadassah Ein Kerem Hospital, Dr. Yuval Weiss, said Saturday evening that the rabbi had undergone "a very light stroke." The rabbi is fully conscious, he said. He will undergo some treatment before being released.

The rabbi underwent a CT scan. He is expected to remain in the hospital for several days, under constant surveillance and medical care.

Shas co-leaders Eli Yishai and Aryeh Deri visited the rabbi during the Sabbath.
