RAMALLAH, West Bank — Hundreds of Palestinian protesters clashed with Israeli security forces Thursday, hurling rocks and burning tires at a West Bank demonstration to show solidarity with Palestinian prisoners held by Israel.

Palestinians have staged protests across the West Bank all week in solidarity with the 4,500 prisoners held by Israel. Four of the prisoners are staging a hunger strike, and the worsening condition of one, Samer Issawi, sparked the latest round of unrest between the protesters and Israeli troops.
