Palestinian president Mahmoud Abbas hospitalised for third time in a week

Palestinian president Mahmoud Abbas returned to hospital on Sunday with a high fever after having undergone ear surgery last week, a source familiar with his condition said.

The source who spoke on condition of anonymity did not provide further details on the condition of the 83-year-old, who was at the Istishari Arab Hospital in Ramallah in the occupied West Bank.

It was the third time he was in hospital in a week.

On Tuesday, Abbas underwent what was called a minor ear surgery. 

Late Saturday, he returned to hospital for further tests and was released after about 30 minutes later.

Official news agency WAFA said the test results had been "excellent".

Abbas was however back in hospital on Sunday around mid-morning and was still there in the afternoon, according to the source.

A statement on WAFA on Sunday afternoon, quoting the hospital director, said tests results were "good" and Abbas's health was "reassuring".

Abbas, a heavy smoker, has a long history of health issues, ranging from heart trouble to a bout with prostate cancer a decade ago.

His health is the subject of regular speculation, with no clear successor identified.

In February, Abbas underwent what was then described as routine medical tests in the United States.

Abbas won a four-year term as president in 2005, but he has remained in office in the absence of elections.

His Fatah party remains deeply divided from Islamist movement Hamas, which runs the Gaza Strip.
