The Palestinians could turn to international bodies to prevent Israel from expanding settlements in the West Bank and east Jerusalem, a senior Palestinian leader said.“We are saying very clearly that if Israel does not stop, then we have to move,” Hanan Ashrawi told reporters on Wednesday during a visit to Jewish settlements in eastern Jerusalem, where hundreds of new apartment units have been approved by Israeli government bodies in recent weeks.The action could threaten the newly relaunched Israeli-Palestinian peace talks. The Palestinians had agreed not to turn to international organizations or join international bodies for nine months, the expected time frame for this round of talks.
