Palestinian Authority Prime Minister Salam Fayyad was hospitalized Monday after suddenly falling ill.

Fayyad was at his office in the PA capital of Ramallah, in Samaria (Shomron), when he was struck down with severe stomach pains.

He was rushed to the city’s Palestine Medical Complex where he was admitted in stable condition.

Doctors told the Bethlehem-based Ma’an news agency the PA prime minister would remain in hospital overnight for observation.

Fayyad is currently also serving as the PA’s acting finance minister following the resignation of Nabil Qassis on March 3. Qassis quit over the PA’s growing budget deficit and resistance he faced over austerity measures he proposed to deal with it.

PA Chairman Mahmoud Abbas considered the option of firing Fayyad after the prime minister accepted Qassis’s resignation while Abbas was on a trip to Saudi Arabia. Abbas has since been mulling instead the possibility of asking economist Mohammed Mustafa, former head of the Palestinian Investment Fund, to form a new government, according to an Arab source.

Mustafa worked at the World Bank in Washington for 15 years, similar to Fayyad, who had spent years working at the International Monetary Fund.
