Israel's Prime Minister Ariel Sharon, 77, has been taken to hospital after suffering a minor stroke.
He had said he was feeling unwell while being driven home from work on Sunday and was taken directly to Jerusalem's Hadassah University Hospital.
Hospital officials say the prime minister is conscious and that his condition is not life-threatening.
The portly 77-year-old is not known to have had serious health problems in recent years.
He is expected to remain in hospital overnight.
Some reports say he lost consciousness briefly before being brought in.
Elections looming
The veteran Israeli politician, who has been prime minister since 2001, recently announced he was leaving the right-wing Likud party he helped found.
He has drawn supporters from both right and left for his new party, Kadima (Forward).
Polls suggest Kadima will come out on top in new elections scheduled for March.
Mr Sharon's health scare came from out of the blue, the BBC's Matthew Price says, but the life of the Israeli leader is a stressful one.
Mr Sharon's deputy and close political ally Ehud Olmert will take over if Mr Sharon is unable to carry out his duties.
Other Israeli politicians have been wishing him well.
His sons Omri and Gilad have come to visit him in hospital.
