Palestinian Authority Prime Minister Salam Fayyad has been hospitalized with an abdominal infection, a government spokesman said Monday night.

Jamal Zakout said the 61-year-old Fayyad felt pain in his abdomen Monday while at his office in the West Bank city of Ramallah.

Zakout said Fayyad went to Ramallah Hospital for tests and was admitted, but it was still unclear whether he would spend the night.

A source close to Fayyad, speaking on condition of anonymity because he is not allowed to discuss the medical diagnosis, said the prime minister had an infected pancreas.

Fayyad suffered a heart attack two years ago while visiting family in the United States.

Since 2007, Fayyad has been prime minister of the Palestinian Authority, the self-rule government that administers parts of the West Bank.
