HAVAT GILAD, West Bank: Israel's prime minister yesterday rejected the US demand for a settlement freeze as unreasonable, moving closer to a collision with the Obama administration, while mobs of Jewish settlers attacked Palestinian laborers and burned West Bank fields.

Six Palestinians were injured in the stone-throwing attacks, meant to protest the removal of several tiny settler squatter camps by the government of Prime Minister Benjamin Netanyahu.

Monday's events highlighted Netanyahu's increasingly difficult balancing act. The hard-line leader is trying to keep his pro-settler ruling coalition together by rejecting President Barack Obama's call for a halt to all settlement activity, at the risk of hurting Israel's all-important relationship with the US.
