The Palestinians are set to ask the UN Security Council to condemn Israeli settlement construction, according to a copy of a draft resolution obtained by the AP news agency.
The move reflects growing Palestinian discontent with stalled US efforts to broker a peace agreement, and is part of a campaign to put international pressure on Israel.
American reaction to the plan has been muted, raising the likelihood that the country would use its veto power in the council to defeat the resolution. Israel has angrily rejected the proposal.
