According to Al Jazeera, a spokeswoman for Israel's prison service said yesterday that the 10 were transferred to a prison clinic for medical supervision.

The spokeswoman didn't say when they were transferred or what medical treatment they were currently receiving.  Sahar Francis of Addameer, a Palestinian prisoner rights group, said the men were moved at different times last week.  The prisoners under medical supervision are reportedly those who have been on hunger strike the longest.

According to the linked article, at least 1,550 prisoners are taking part in the strike, although activists have said the figure is as high as 2,500 out of the 4,600 Palestinians held in Israeli prisons.  These figures line up with those reported by the Associated Press.  Most of the hunger strikers began refusing food 19 days ago; a smaller core has been striking for periods ranging from 40 to almost 70 days.
