Israel released a Palestinian human rights worker who four years ago was declared a "prisoner of conscience" by Amnesty International, a West Bank human rights organization said Saturday.

The release coincided with further unrest in the Israeli-occupied West Bank and Gaza Strip, where at least nine Palestinians were wounded Saturday by army gunfire or rubber bullets, state-owned Israel Radio reported.An army spokesman said it had reports that two people were wounded in Gaza City and a gasoline bomb was thrown at an army patrol in the West Bank town of Ramallah, but no one was injured.
