The Palestinian president, Mahmoud Abbas, was hospitalized in the West Bank on Sunday, doctors and Palestinian officials said, giving conflicting accounts of the leader’s condition.

It is the third time in less than a week that Mr. Abbas, 82, has been hospitalized. He is expected to remain in the hospital at least overnight.

Mr. Abbas underwent minor ear surgery on Tuesday but briefly went back into Istishari Hospital in the West Bank city of Ramallah during the night from Saturday to Sunday, the official Palestinian news agency Wafa said.

He was then rushed back later Sunday, for what doctors described only as “medical tests”.

Dr. Saed al-Sarahneh, medical director of the private hospital, said late Sunday that Mr. Abbas had arrived in the morning for medical tests following up on surgery he had three days earlier in his middle ear. “All the tests are normal and his medical condition is reassuring,” he said.
