Israeli Prime Minister Ariel Sharon suffered a mild stroke at his office Sunday and was rushed to a Jerusalem hospital.
Doctors at Hadassah hospital said they performed tests on Mr. Sharon and that his condition had improved since his arrival. They said the 77-year-old was to remain hospitalized for several days.
The White House and Palestinian leader Mahmoud Abbas expressed hope for Mr. Sharon's speedy recovery.
Earlier this year, Mr. Sharon orchestrated the most dramatic shift in Israeli politics in decades, after ordering the evacuation of Israeli settlers from the Gaza Strip.
He then broke with his right-wing Likud Party that opposed the withdrawal and formed a centrist coalition to pursue further negotiations with the Palestinians.
