Israeli doctors say they plan to bring Prime Minister Ariel Sharon out of a medically-induced coma Monday and assess the damage caused by a massive stroke.
Doctors at Hadassah hospital in Jerusalem said tests taken Sunday showed slight improvements in Mr. Sharon's brain. But he remains in critical condition, and doctors said that last week's stroke likely caused significant brain damage.
They say he will probably not be able to return to power even if he survives.
Meanwhile, the top Palestinian negotiator Saeb Erekat called on Israel's acting Prime Minister Ehud Olmert to renew peace talks, once Israel's political transition is resolved.
Mr. Olmert has vowed to carry out Mr. Sharon's work on security, social and economic issues. Elections for a new prime minister are set for March.
